----------------------------------------

The crashes appear to be occurring in {{libssl}}:

Which version of {{libssl}} are you using? If possible, can you upgrade to the latest version of {{libssl}}? It would also help if you could install a version of {{libssl}} with debug symbols.

That being said, there isn't anything jumping out here that looks like Asterisk doing something wrong. If we can look at the SSL library's symbols, we may be able to determine what exactly is going wrong - but there's a good chance that this is a bug in that library, and not Asterisk.

> Hi everyone,
> we're using Asterisk with {{res_pjsip}} and since version 12.4.0 it crashes once a day with a segmentation fault:
> {code}kernel: [665291.790543] asterisk[2160]: segfault at 7fda5c16cdf0 ip 00007fdb0f7ed4de sp 00007fd9c78d7c18 error 4 in libc-2.19.so[7fdb0f75d000+19f000]{code}
> We used {{libpjsip2}} (2.1.0.0.ast20130823-1) from Debian packages and also compiled version 2.2.1, 2.3 and git (master at 2014-10-06) from source. This didn't fix the problem.
> The issue is not bound to system load. The problem occurs even with 0 open channels.
> Any help would be greatly appreciated!
> Best regards,
> Tobi
