[asterisk-bugs] [JIRA] (ASTERISK-23328) Asterisk crash in ast_cdr_setapp() at cdr.c

[David Hajek (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-23328?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=215590#comment-215590 ] 

David Hajek commented on ASTERISK-23328:
----------------------------------------

We do some investigation as well. Our dialplan was this:

;; This context is called from Queue() 
;; Our member interface is similar to this: Local/10001 at dakqueue/n
[dakqueue]
exten => _X.,1,DoSomething()
exten => _X.,n,Dial(...,M(answer))
exten => h,1,DoCleanup()

[macro-answer]
exten => s,1,DoSometing()
exten => s,2,Macro(somethingelse)
exten => s,3,Gosub(cleanup)

We rewrote macro-answer to remove Macro(somethingelse) and Gosub(cleanup). We think that calling Gosub() from Macro() can be a bad idea. Can you confirm? Can you imagine this can be the issue?

We will keep running this configuration for couple of days and I will get back with results. Next step can be to completly get rid of Macro() and use Gosub() only.

> 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.
