 |
|
Hello!
I occasionally can see warnings like these during *idle* times in
asterisk log (asterisk 13.7.2):
[2016-06-05 06:11:51] WARNING[27817] pjsip: sip_transactio Unable to
register REGISTER transaction (key xists)
[2016-06-05 06:11:51] WARNING[27817] pjsip: sip_transactio Unable to
register REGISTER transaction (key exists)
Nothing more. The third REGISTER package works as expected.
What's going on:
My phone regularly (each 7.5 minutes) sends REGISTER. Sometimes, those
REGISTERs are denied like seen above (mostly already the second REGISTER
works and no third REGISTER is needed).
The reRegistering of the phone normally works like this (as seen in
wireshark):
-> REGISTER 06:04:19:285
<- 401 Unauthorized 06:04:19:287
-> REGISTER 06:04:19:316
<- 200 OK 06:04:19:376
If warnings happen like the one mentioned above, the following can be
seen in wireshark:
-> REGISTER 06:11:49:359
<- 401 Unauthorized 06:11:49:362
-> REGISTER 06:11:49:392 Unable ...
-> REGISTER 06:11:49:876 Unable ...
-> REGISTER 06:11:50:868
<- 200 OK 06:11:51:634
The second, third and fourth register package look completely identical
to me according wireshark regarding SIP.
Notice the big latency between the fourth register and the following 200
OK: there are nearly 0.8 seconds in between in the problem case - but
normally, there are just 0.06 seconds between REGISTER and 200 OK!
What happened during these 0.8 seconds? Asterisk (and the complete
machine) has been completely idle at this time - there wasn't any call
or anything other to process.
I've got the complete wireshark trace of the situation described above.
Any idea?
Kind regards,
Michael

Those key exist messages are due to a race condition. From what I've
seen in the code the messages seem to be benign.
How may endpoints are registering to your Asterisk? How often?
Do you use realtime? Is your realtime database on the same machine?

It should be impossible - there couldn't be any race condition at this time.

1 device, which registers 2 different numbers *serially*. Asterisk
didn't do any other things at the time those warnings came up. It was
idle. Completely.
Each 7.5 minutes.

No.

Please - could you tell, where you found them? Unfortunately, I wasn't
able to find them!
Thanks,

Those messages are created inside the PJSIP library code. Specifically in the
sip_transaction.c file. Asterisk is just passing the message on.
