[asterisk-bugs] [JIRA] (ASTERISK-26836) res_pjsip: Memory corruption of endpoint

[Richard Mudgett (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-26836?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=235898#comment-235898 ] 

Richard Mudgett commented on ASTERISK-26836:
--------------------------------------------

Memory corruption issues are very difficult to find and fix without a starting place of what is being misused.  I'm a little surprised that you aren't getting a crash because of the memory corruption.

Please enable MALLOC_DEBUG with DONT_OPTIMIZE.  These two options do not affect performance too much so you can enable them on production systems while looking for the memory corruption.

Are you using bundled pjproject?

> This is a recurring issue on all my production servers. When it happens, Asterisk stops serving SIP clients properly.
> It reads to me as a memory leak as it's just one character incrementing.
> The latest time, it occurred shortly (but not immediately) after I issued a 'pjsip reload', but it may have just been a coincidence. I've included the timing in the CLI log.
> Seems to happen every 4 or 5 days requiring a 'killall -9 asterisk' and 'database deltree registrar' in order to get working again. I can't remember, but the first time it happened, Asterisk would not respond to 'core stop now' or 'core restart now' so I had to do killall. But I havent tried 'core stop now' during subsequent issues.
> This issue stops all endpoints from communicating with Asterisk. Even ones that have already registered.
