[asterisk-bugs] [JIRA] (ASTERISK-24144) Asterisk 12.4.0 Crashes with DTLS

[Matt Jordan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-24144?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=221093#comment-221093 ] 

Matt Jordan commented on ASTERISK-24144:
----------------------------------------

There is not enough information in the backtrace. All the backtrace shows is that a scheduled call to {{dtls_srtp_handle_timeout}} occurred and this led to an abort in OpenSSL.

You'll need to install a version of OpenSSL that has debug symbols in it. Even then, this may not be a bug in Asterisk but in OpenSSL.

> Recently, we updated our system from 11.6.0 to 12.4.0 with DTLS support.
> Asterisk is used only to make outgoing calls. (Chrome -> Asterisk -> VoIP Gateway)
> We are seeing random crash with exception:
> Program terminated with signal SIGABRT, Aborted.
> #0  0x00007f8cee12bf79 in __GI_raise (sig=sig at entry=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:56
> It is really random, at a time with 200 concurrent calls, it was working fine and at other time, it crashed only on 100 concurrent calls.
> I have also attached backtrace logs with this.
