Segmentation fault Asterisk 13.19.0


Hello Team!

Hope you can help me on this.
I have Asterisk instance running on VMWare. 4GB RAM, 1 core Intel® Xeon® CPU E5-2630L v3 @ 1.80GHz

We’ve been running Asterisk 13 for about six months already and had no issues. We are using res_pjsip with approx 100 endpoints with static contacts and registrations. First we had version 13.16, then updated to 13.19 as soon as it was released.
Recently it started to segfault with errors like this:

kernel: asterisk[24600]: segfault at 0 ip 00007fe28480e921 sp 00007ffdee61a238 error 4 in[7fe2846a9000+1b8000]

It produced core dump (latest backtrace attached). Asterisk crashes and safe_asterisk is unable to restart it so i had to manually start it again (with pgrep script later).
I tried to update it to 13.20, 15.2 and downgrade it to 11.21, disabling pjsip and enabling only SIP, but nothing helps it still crashed almost every hour even in idle state when there are no calls at all.
Then i made fresh CentOS install on different(physical) ESX host and compiled asterisk 13.19 from scratch again. It worked the whole night without issues but crashed again in the morning with segfault. Asterisk give no messages, on debug it just unregisters all modules and stops.

I would really appreciate your helps. Let me know if i need to provide any more information or logs.

Thank you.backtrace.txt (81.1 KB)


There is no team here. It is a peer support forum.

You need to rebuild Asterisk with compiler optimisation disabled for the backtraces to be of much use.


Hello David,
I will recompile it and get backtraces from the next crash.
Thank you.
