[asterisk-dev] Task Processor Issue ASTERISK-26145

[Ross Beer]

I think this is related to the following review board link:


https://gerrit.asterisk.org/#/c/3320/


When using ODBC storage with VM there is a backlog in processing MWI notify messages. This patch has helped the issue, but not totally resolved it. There is debate on the review board if this is needed by from my experience it is!


When using ODBC storage for VM are only registered devices checked for new messages or all peers? Does Asterisk try to send alerts to every peer that has voicemail even if its not registered?

Hi,


Just has the same issue on a different test box:


pjsip/distributor-000000cc                         68046          0          5        450        500

pjsip/distributor-000000cd                         68846          0          5        450        500

pjsip/distributor-000000ce                         79573        533         12        450        500

pjsip/distributor-000000cf                         65862          0          9        450        500


This happens daily on multiple test servers.


Can anyone help?

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
