[asterisk-bugs] [JIRA] (ASTERISK-26601) app_voicemail: task_processor backed up

[Richard Mudgett (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-26601?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=234766#comment-234766 ] 

Richard Mudgett commented on ASTERISK-26601:
--------------------------------------------

This is the first run you have shown the pjsip/mwi task processors hitting their limit.  I don't know if the pjsip/mwi task processor backlog is because of ASTERISK-26548.  When you gathered the data the task processor backlog had cleared itself, there were no tasks queued in any other task processors, and the system only had about 10 calls on it.  I also think your turning "pjsip set logger on" and then monitoring activity for only 20 seconds is too short to determine if pjsip is not processing packets before killing asterisk to restart it.  You don't even know if any packets were actually sent to the server.

Nothing is showing that this is anything other than a brief transient event that self corrects.

> I had Asterisk 14.1.0-rc1  running for 3 weeks, and all of the sudden PJSIP stopped working. Nothing in the console.
> I had time to save the task_processor output before restarting asterisk.
> After doing a restart to get the system back on I can see this in the log files:
> taskprocessor.c: The 'app_voicemail' task processor queue reached 500 scheduled tasks.
> I did not find any message concerning taskprocessor before the system stopped functioning.
> I'm aware that I am running an RC release, but looking at the release note, there were nothing concerning deadlock so I was thinking updating later.
