Richard Mudgett commented on ASTERISK-25455:
--------------------------------------------

We suspect that you have a deadlock occurring within Asterisk. Please follow the instructions on the wiki [1] for obtaining debug relevant to a deadlock. Once you have that information, attach it to the issue. Be sure the instructions are followed exactly as the debug may otherwise not be useful.

Thanks!

> Asterisk intermittently deadlocks during initial loading of pjsip endpoints. It seems to depend on number of endpoints loaded. With small number of endpoints (up to a 100) it loads ok most of the time. With several hundreds of endpoints it deadlocks sometimes. With several thousand of endpoints it deadlocks most of the time.
> Attached are backtrace and output of "core show locks". The testing was done on asterisk 13.6.0-rc2
