Hello Asterisk users,We noticed that on Asterisk 12 zombie processes are being generated - They are released after a while, but we have around 10-20 zombie processes running.


We are not sure if this is a normal behavior or an issue. 


We saw in the documentation that the bridging module creates zombie processes - is it related?


Thank you,
Yaron.

Hello Mathew,In the following tutorial it says that channel are marked with ZOMBIE flag. From your response I assume it has no connection to my problem.
https://wiki.asterisk.org/wiki/display/AST/Asterisk+12+Bridging+Project



Regrading the zombie processes issue we are having. We have debug taken from the server during such process is invoked. If you want I can attache it.


Furthermore,  in recent days we have had a number of reboots. Most of our servers are on release 12.2.0.RC1, and we have just upgraded to 12.6.1 on one of the servers. since the upgrade we have't had a reboot, but it is too early to be sure.


Somehow the core files are not written - in the log file it says - Executable '/ivr/app/asterisk/sbin/asterisk' doesn't belong to any package. Do you have any idea?


Thank you,
Yaron.

Mathew,
When I run 'ps -ef|grep asterisk' the following processes are displayed:
root      6861     1  0 Aug27 ?        00:00:00 /bin/sh /ivr/app/asterisk/sbin/safe_asterisk -U asterisk -G asterisk -C /ivr/app/asterisk/etc/asterisk/asterisk.conf
asterisk  8062  6861  3 Oct27 ?        00:44:56 /ivr/app/asterisk/sbin/asterisk -f -U asterisk -G asterisk -C /ivr/app/asterisk/etc/asterisk/asterisk.conf -vvvg -c
root     20776  2200  0 11:20 pts/2    00:00:33 tail -f asterisk.log
asterisk 23076  8062  0 17:01 ?        00:00:00 [asterisk] <defunct>
asterisk 23897  8062  0 17:03 ?        00:00:00 [asterisk] <defunct>


also when I run top the same amount of zombie processes are displayed:
Tasks: 185 total,   1 running, 182 sleeping,   0 stopped,   2 zombie



Regarding the AGI - we are using AGI in order to run php scripts for external logic. I have printed the PIDs of the php scripts and none of them are related to the PID's of those zombie processes.
Do you have any idea how to find out what are these processes?
Yaron.

Hello Mathew and everyone,We are still having reboots on our asterisk servers. The latest 12.6.1 release doesn't fix the issue.


We have the core files of the latest reboots and also debug taken during the reboot.


We would like to open an issue. What kind of information you need for the issue? 


Thanks,
Yaron.

Hello Asterisk users & developers,I have opened an issue few days ago regarding the crash and the zombie processes. I haven't received any response and it has't been assigned.
If something is wrong or missing with the issue please get back to me and I will handle it.


Please look into it because we still have crashes every day or two, and we can't reproduce the issue in our lab with a simulator. 


Thank you,
Yaron.

Mathew,We are aware that this is an open source product, and our expectations are clear. 
All we are asking is that once there is someone assigned to the issue, he will guide us in what other data or tests should be performed in order to diagnose and fix the issue in the shortest time. 


Sorry if the message is not understood. 
Yaron
