How to find out which child is unresponsive?

[feredi]

I get Supervisor: killing unresponsive child 13463 in yate's log and then suddenly yate is restarted afterwards.
How can I find out which component is causing this bug? No further information is included in Yate's log. A partial log of when the error occurred is found below:

Note: Debug level is already set to maximum value of 10

Any help is highly appreciated

Hi,

Usually you have more clues in the log. Please upload a bigger log and specify how many external scripts you are running and of what type. Problems usually indicate a bug in the external script.

Hi Monica,

Thanks for your reply.

A more complete log is included below. Some unfamiliar logs you see are those added to source code by me and I forgot to remove them later ;-) those like (Connecting peersssssssssssss or Here is ToneDetectHandler coming in action  ). If you need more log just let me know and I'll attach a more complete log file.
I only have a php script running which is acting as an IVR. It's written based on ivr-sample.php available on internet. (https://github.com/shimaore/yate/blob/master/share/scripts/ivrsample.php). Of course I have made a few changes on it to customize it for my needs. So you think this php script is causing the problem? Do you have any idea how can I find out which piece of its code is doing something wrong? As you can see its debugging is turned on. The last thing this php script had done before the crash occurred was ivr1::SetState('sig/15998', currencyPlay') which is simply assigning currencyPlay to a global variable and the next thing done after an unresponsive child being detected by Yate was ivr1: Found table operation 'play' which is when a file is going to be played to caller.

And it happened again! Log file is attached.

[feredi]

I had a global array in my PHP code. I changed it to be a class member and solved a few memory leaks in my code and the problem never occurred again so far. Thank you Monica for directing me to the right direction and pointing out the possibility of having a bug in external script.

[feredi]

Sorry for opening this thread again.

The same script which is now working on my server is showing same symptoms as indicated in above logs on different server. Any idea what could be wrong here?
UPDATE:
Supervisor: killing unresponsive child 29157 is showing up in logs and child 29157 is PID of yate process itself. I used top to get pid. my global script can also be found in top output but it has a different pid. That's why I guess the problem isn't related to external script.

Thanks

If Yate is waiting for a message to be handled by your script and the message is not handled in reasonable time (10 seconds, as fas as i rememenber), Yate will be restarted by the supervisor. So, although it may see that Yate is unresponsive, the cause could be the script.

Please provide a log and if you started yate with the -C option, look at the core left by the restart and please paste it also.
