[asterisk-bugs] [JIRA] (ASTERISK-26202) Random crashes when a channel joins a bridge

[Joshua Colp (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-26202?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=231505#comment-231505 ] 

Joshua Colp commented on ASTERISK-26202:
----------------------------------------

Your backtrace appears to contain a memory corruption. We need one or both of the following items to continue investigation of the issue:
1. Valgrind output. See https://wiki.asterisk.org/wiki/display/AST/Valgrind for instructions on how to use Valgrind with Asterisk.
2. MALLOC_DEBUG output. See https://wiki.asterisk.org/wiki/display/AST/MALLOC_DEBUG+Compiler+Flag for instructions on how to use the MALLOC_DEBUG option.

Note that MALLOC_DEBUG and Valgrind are mutually exclusive options. Valgrind output is preferable, but will be more system resource intensive and may be difficult to get on a production system. In such a case, you may have better luck getting the necessary output from MALLOC_DEBUG.

> Hi there,
> Today I encountered several SEGV/ABORT crashes. The backtraces are different but in the logging file it seems that in most cases the last event is "Channel X joined 'simple_bridge'".
> Thanks,
