[asterisk-bugs] [JIRA] (ASTERISK-23328) Asterisk crash in ast_cdr_setapp()

[Matt Jordan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-23328?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=215423#comment-215423 ] 

Matt Jordan commented on ASTERISK-23328:
----------------------------------------

If you still have the {{core}} file, using gdb, can you print out what chan points to in frame 1? The commands should be:

{noformat}
# frame 1
# p *chan
{noformat}

Somehow, when the channel is returning from the AGI it no longer has a valid CDR object on it. I can see that occurring for two reasons:
# The channel has already been destroyed, which would indicate a ref counting problem somewhere. If that happens to be the case, it will be important to understand the sequence of events that led up to the crash. A DEBUG log may be necessary, or at least steps that reproduce the problem.
# A masquerade occurred and the channel that replaced the channel in the AGI never had a CDR object allocated on it - or something equally strange.

Dumping what chan pointed to will help determine what occurred.

> We are experiencing random asterisk crash (segfaults) on a busy server, which is doing about 50k calls a day. We see asterisk crash every other day.
> This server is running a callcenter and in addition to regular in/out calls this server is processing callfiles (about 3 per second). Some AGI dialplan scripts are processed using FastAGI over tcp sockets.
> We see that all crashes are in ast_cdr_setapp() - we tried both 1.8.24 and 1.8.25.
> For CDR we use cdr_adaptive_odbc with MySQL backend.
