[asterisk-bugs] [JIRA] (ASTERISK-26956) Exceptionally long voice > queue length queuing

[Ted G (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-26956?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=236689#comment-236689 ] 

Ted G commented on ASTERISK-26956:
----------------------------------

Its very difficult to diagnose because all this debugging stuff puts an enormous strain on my system.

Here is what I have noticed.  It seems to be mostly local channels, i.e.: Local/s at announce-0000015b

My purpose for these is to play announcements into conferences so that everyone can hear them and thus to create these I do the following:

Create a call file like so and move it to: /var/spool/asterisk/outgoing

Channel: Local/s at announce
Set: ARG1=11
Application: Playback
Data: /opt/sipx/wav/msg1&/opt/sipx/wav/msg2

Which triggers an event in extensions.conf:

[announce]
exten => s,1,NoOp
same => n,Answer
same => n,ConfBridge(${ARG1},bridge,user)
same => n,Hangup

So maybe something with that method is causing these channels to deadlock somehow.  Ive been doing this for more than a year and this problem only cropped up a ~week ago.

> Hello,
>   I am getting tons of these messages in my logs a few times a day which causes my system to be completely dead:
> [Apr 20 21:39:15] WARNING[24491][C-00000197]: channel.c:1162 _astqueue_frame: Exceptionally long voice queue length queuing to Local/s at announce-0000015b;1
> [Apr 23 15:32:06] WARNING[20645] channel.c: Exceptionally long voice queue length queuing to CBAnn/12-000001f0;1
> I am having a very difficult time figuring out what is causing it other than 'its a channel deadlock' which doesn't really tell me how to fix the issue.  This just started happening around ~6 days ago.
> This problem is extremely catastrophic as the only fix is to completely restart the asterisk system.
> Included are backtrace and core-show-locks logs.  Please assist this desperate fool. :)
