Posted: Thu Apr 15, 2021 2:14 am Post subject: [Freeswitch-users] Internal Interface suddenly freezes

Hey guys,
Its still happening.
I tried to set cacheable=true to reduce the calls to my register.lua. ( In case It was the register.lua causing all of this )
But it seems like thatâ€™s not helping too. The internal interface freezes about as much as often as beforeâ€¦

I guess my register.lua I sent doesnâ€™t have any obvious mistakes too â€¦

Is it possible that some failed database-connection doesnâ€™t get re-established, and thatâ€™s holding up the whole registration-queue?
Does anybody know where I could set freeswitch-db-reestablish timeouts? Very Happy

Or does that even exist?

Regards,
Stefan

Hey,
I also thought of the load at first, but I set up a new server with only about 20 extensions on it.
So it looks like its not because of the load â€¦ The concurrent calls never exceed 10.

Its strange â€¦ im thinking of rewriting my register.lua from ground up, and get rid of things I donâ€™t need.

This happens under high load with a lot of presence involved. Suddenly Freeswitch internal profile stops responding and after a while (some minutes) it responds again. During that time, no register requests are answered at all. Only a few XML-Curl requests are sent to the server, but they do not contain the user info (which are needed for registrations) and are related to mod_voicemail.c etc.

This time I turned up the logging to 9 while it was happening.
This is what I found:

While its happening, a Register request causes the following to be logged:

And thatâ€™s it. it doesnâ€™t even execute my register.lua anymore, I just tries to update an existing Register transaction.
When I start an ngrep on port 5060, all I see is the register, no unauthorised or ok response.

While a Register Request after I restarted freeswitch and everything worked again looks like this:

...

The last entry â€œConnect to databaseâ€ is already a consoleLog from my register.lua.
From here on out everything works great again â€¦

So, do you think it could still be true that one request to my register.lua holds up all subsequent requests?

Thank you very much!

I will try to return a not found and add debug lines to the register.lua.
I will let you know If that helped.

Hi,

If you don't wish to serve an action from your Lua script, you must return not found.

This is from confluence doc:

If your LUA application receives a request and you don't wish to serve dialplan or like to fallback to plain XML dialplan, then you should return the following "not found" result.

Quote:

<?xml version="1.0" encoding="UTF-8" standalone="no"?><document type="freeswitch/xml"> <section name="result"> <result status="not found" /> </section></document>

Best regards,

Mircea

Hi,

The lua script is called on a directory request.

Your know, autoload_configs, lua.conf.xml:

<param name="xml-handler-script" value="register.lua"/>

<param name="xml-handler-bindings" value="directory,dialplanâ€/>

Maybe the dialplan in the xml-handler-bindings is doing something I donâ€™t want â€¦

In the register.lua I do basic sanity checks, and of course a database query that returns the user-data.

After that I generate the xml that gets sent to freeswitch.

Yesterday I added cacheable=â€œ120" to the <user> tag.

Thats no solution of course, but it looks like when the data is in the cache the lua script doesnâ€™t get called.

So maybe the error wonâ€™t occur as often as before â€¦

But, I have an idea, maybe you can confirm this.

With dialplan enabled in xml-handler-bindings, the lua script is also called on calls, not just on registrations.

( I think thatâ€™s necessary to authenticate the users on an outgoing call, please correct me if im wrong )

In the register.lua I only handle directory-requests and action==user_call.

All other requests to my register.lua are unhandled and therefore I donâ€™t return any xml at all.

Maybe I get a request to my register.lua that is not a directory-request and not a user_call and since I donâ€™t return a xml, Sofia hangs.

Does that sound plausible?

Thank you in advance!

Regards,

Stefan

I just found an issue on jira, where it seems someone had the same problem I have.
https://freeswitch.org/jira/browse/FS-3328
I donâ€™t have mod_xml_curl enabled though.

But knowing that sofia can handle only one register at a time and then blocking all subsequent Registers is a good starting point â€¦

The one common element is your Lua script.

I am certainly no expert on script writing, but I have seen a number of problems on the mailing list over the years with scripts doing â€œtoo muchâ€ work during critical sections of the dialplan. Perhaps there is a race condition?

Hope this helps.

Thank you for your answer!

Hmm, I also tested it on two completely different servers ( no virtualization ) and the problem exists on both.
Im also going to try it on a third server, also completely different, but I cant really image that this is a hardware-thing â€¦

We also have many freeswitch servers in production ( Exactly the same hardware as the server with the problem ).
The only difference is that one of those servers handles registrations, and one doesnâ€™t.
The one handling the registrations has the problem, the other one doesnâ€™t.

Its really strange â€¦

That looks to be more on the hardware side than software. Itâ€™d be an extremely coincidence those versions and all those OS have some issue somewhere.

Change hardware.

Hi everbody, I have a little bit of a problem. Im using Version 1.10.3. ( but this problem also occurs on version 1.4.18 ) Sometimes the internal Sofia interface just stops responding to SIP Requests. It sometimes happens once every day, and sometimes once a week. It happens at completely random times, like one day in the morning, and the next day in the middle of the night. The freeswitch.log gives me nothing, its like the Sofia interface was stopped. When I try to restart the interface with "sofia profile internal restartâ€ nothing happens. The fs_cli just remains stuck with that command. The solution is to restart the freeswitch service. Sometimes when I recognise it too late, for example in the middle of the night, it seems like the problem solves itself after about 2 hours. The profile just starts working again, without somebody doing anything. I have checked a variety of things, including the firewall & fail2ban, network connection, made sure watchdog is disabled, and also tested it on different Debian-versions and freeswitch versions. It seems this problem occurs on every freeswitch version i have tested. The external-profile on the other hand, keeps working like nothing happened. Both Interfaces listen on the same network-device with a public ip. The only difference is, the internal profile uses a Lua file to handle registrations. Has anybody come across anything similar? Any help is much appreciated!

What happens if you donâ€™t connect to a db and authorize everything? (I hoping youâ€™re not in a production system)

The last entry â€œConnect to databaseâ€ is already a consoleLog from my register.lua.Â
From here on out everything works great again â€¦Â

So, do you think it could still be true that one request to my register.lua holds up all subsequent requests?

Thank you very much!

Hi,Â

Â

If you don't wish to serve an action from your Lua script, you must return not found.Â

Â

This is from confluence doc:

Â

If your LUA application receives a request and you don't wish to serve dialplan or like to fallback to plain XML dialplan, then you should return the following "not found" result.

Quote:

<?xml version="1.0" encoding="UTF-8" standalone="no"?><document type="freeswitch/xml">Â <section name="result">Â Â Â <result status="not found" />Â </section></document>

Â

MirceaÂ

Hi,Â Â
Â

The lua script is called on a directory request.Â

Your know, autoload_configs, lua.conf.xml:Â

Â

<param name="xml-handler-script" value="register.lua"/>

<param name="xml-handler-bindings" value="directory,dialplanâ€/>

Â

Maybe the dialplan in the xml-handler-bindings is doing something I donâ€™t want â€¦Â

Â

In the register.lua I do basic sanity checks, and of course a database query that returns the user-data.

After that I generate the xml that gets sent to freeswitch.Â

Â

Yesterday I added cacheable=â€œ120" to the <user> tag.

Thats no solution of course, but it looks like when the data is in the cache the lua script doesnâ€™t get called.Â

So maybe the error wonâ€™t occur as often as before â€¦Â

Â

But, I have an idea, maybe you can confirm this.Â

With dialplan enabled in xml-handler-bindings, the lua script is also called on calls, not just on registrations.Â

( I think thatâ€™s necessary to authenticate the users on an outgoing call, please correct me if im wrong )

In the register.lua I only handle directory-requests and action==user_call.

All other requests to my register.lua are unhandled and therefore I donâ€™t return any xml at all.Â

Â

Maybe I get a request to my register.lua that is not a directory-request and not a user_call and since I donâ€™t return a xml, Sofia hangs.

Â

Does that sound plausible?

Â

Thank you in advance!

Â

Regards,Â

Stefan

Â
The one common element is your Lua script.
Â
I am certainly no expert on script writing, but I have seen a number of problems on the mailing list over the years with scripts doing â€œtoo muchâ€ work during critical sections of the dialplan. Perhaps there is a race condition?
Â
Hope this helps.

Thank you for your answer!
Â
Hmm, I also tested it on two completely different servers ( no virtualization ) and the problem exists on both.Â
Im also going to try it on a third server, also completely different, but I cant really image that this is a hardware-thing â€¦Â
Â
We also have many freeswitch servers in production ( Exactly the same hardware as the server with the problem ).Â
The only difference is that one of those servers handles registrations, and one doesnâ€™t.
The one handling the registrations has the problem, the other one doesnâ€™t.Â
Â
Its really strange â€¦Â

That looks to be more on the hardware side than software. Itâ€™d be an extremely coincidence those versions and all those OS have some issue somewhere.

Change hardware.Â

Hi everbody,Â

I have a little bit of a problem.Â
Im using Version 1.10.3. ( but this problem also occurs on version 1.4.18 )

Sometimes the internal Sofia interface just stops responding to SIP Requests.Â
It sometimes happens once every day, and sometimes once a week.Â
It happens at completely random times, like one day in the morning, and the next day in the middle of the night.Â
The freeswitch.log gives me nothing, its like the Sofia interface was stopped.Â

When I try to restart the interface with "sofia profile internal restartâ€ nothing happens. The fs_cli just remains stuck with that command.

The solution is to restart the freeswitch service.

Sometimes when I recognise it too late, for example in the middle of the night, it seems like the problem solves itself after about 2 hours.Â
The profile just starts working again, without somebody doing anything.

I have checked a variety of things, including the firewall & fail2ban, network connection, made sure watchdog is disabled, and also tested it on different Debian-versions and freeswitch versions.Â
It seems this problem occurs on every freeswitch version i have tested.Â

The external-profile on the other hand, keeps working like nothing happened.Â

Both Interfaces listen on the same network-device with a public ip.Â
The only difference is, the internal profile uses a Lua file to handle registrations.Â Â

Has anybody come across anything similar?Â

Any help is much appreciated!

Posted: Thu Apr 15, 2021 6:15 am Post subject: [Freeswitch-users] Internal Interface suddenly freezes

Hi David,
Sadly this happens on a production system. But by now I have two other dev-servers suffering the same issue.
Good idea, im actually in the process of testing a system with the database on the same host, in case it really is the database-connection.

But I think you mean enabling accept-blind-reg right? so that the register.lua isnâ€™t even executed.
I will try that. But if there really is a connection-issue with the database, I expect another issue to arise, since I also need the db connection for incoming and outgoing calls as well as the freeswitch-core database.

But lets see.
It can take a while, because this happens in completely random intervals, but Iâ€™ll let you know.

Thank you very much,
Regards

( With extra debugging lines in my register.lua and a not found xml like you suggested if the result is empty )

This time I turned up the logging to 9 while it was happening.
This is what I found:

While its happening, a Register request causes the following to be logged:

nta.c:2880 agent_recv_request() nta: received REGISTER sip:xxxxx SIP/2.0 (CSeq 73038)
nta.c:3012 agent_recv_request() nta: REGISTER (73038) going to existing REGISTER transaction

And thatâ€™s it. it doesnâ€™t even execute my register.lua anymore, I just tries to update an existing Register transaction.
When I start an ngrep on port 5060, all I see is the register, no unauthorised or ok response.

While a Register Request after I restarted freeswitch and everything worked again looks like this:

No, I mean in your lua, donâ€™t connect to any db and just accept all registrations.Â

If you still see it, then thereâ€™s something in your lua. If you donâ€™t, itâ€™s the db (connection or otherwise)

I think, I have a similar problem with registers (and presence) via XML-Curl. Freswitch is not sending a Curl request to the server then (as we grepped on the network interface).
This happens under high load with a lot of presence involved. Suddenly Freeswitch internal profile stops responding and after a while (some minutes) it responds again. During that time, no register requests are answered at all. Only a few XML-Curl requests are sent to the server, but they do not contain the user info (which are needed for registrations) and are related to mod_voicemail.c etc.

Hi,Â

Â

If you don't wish to serve an action from your Lua script, you must return not found.Â

Â

This is from confluence doc:

Â

If your LUA application receives a request and you don't wish to serve dialplan or like to fallback to plain XML dialplan, then you should return the following "not found" result.

Quote:

<?xml version="1.0" encoding="UTF-8" standalone="no"?><document type="freeswitch/xml">Â <section name="result">Â Â Â <result status="not found" />Â </section></document>

Â

Â

Best regards,Â

MirceaÂ
