[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=215706#comment-215706 ] 

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

Yes, AGI (where it crashed) was called from [macro-answer] context. Actually there are two AGI scripts called.

;; This is how it looks when it crashes
[macro-answer]
exten => s,1,AGI(script1)
exten => s,n,AGI(cc/dialer_set_user.php) ;; It always crashed here
exten => s,n,Macro(somework)
exten => s,n,Gosub(somework)

;; This is after rewriten
[macro-answer]
exten => s,1,AGI(script1)
exten => s,n,AGI(cc/dialer_set_user.php)
exten => s,n,SomeDialPlanWorkHere   ; No Macro
exten => s,n,SomeOtherDialPlanWorkHere ; No Gosub

Its a bit early to do some final resolutions, but its running for 6 days without crash. 

Regarding calling Gosub from Macro I'm refering to http://www.voip-info.org/wiki/view/Asterisk+cmd+Macro

"You really shouldn't be calling a Gosub routine from Macro. We've already had to deal with some really odd interactions between the two. If you're going to make the jump to Gosub, go completely over and only use Gosub. Don't use Macro in conjunction with Gosub (Tilghman, May 2010)."

> 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.
