[asterisk-dev] Task Processor Issue ASTERISK-26145

[Ross Beer]

Hi All,


I am still experiencing a task processor issue which stops Asterisk 13 processing packets. The task processor shows the following:

Processing appears to be fairly evenly distributed across the threads, however, one thread appears to get flooded. I though this could be related to voicemail and MWI https://issues.asterisk.org/jira/browse/ASTERISK-26229 but I am currently testing the patch and it's not showing a queue on the new taskprocessor for app_voicemail.


What features use the 'pjsip/distributor' and how can I identify what is causing the backlog?


One thing I did notice in the latest back trace, was a call pickup was being done a the time of the issue. Is there a lock that isn't released here?


Kind regards,


Ross
