Joshua Colp commented on ASTERISK-26601:
----------------------------------------

Incoming requests are matched to an endpoint which in your setup is done using a database query. Each thread trying to identify who the request is from was blocked waiting for the database, which meant messages piled up, and no responses could be sent (as the message hadn't even been processed yet).

> 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.
