Joshua Colp commented on ASTERISK-25871:
----------------------------------------

This is the same issue as ASTERISK-25275, just in this case the memory is such that it is blocked instead.

I'd suggest upgrading to the latest pjproject from its SVN, changes have gone in which may fix this issue.

> We use asterisk to mix WEBRTC streams and encounter random deadlocks.
> When there are 2 or more participants in a conference (the number is not relevant, the deadlock may occur when there are only 2 participants and work fine when there are 140, and sometimes vice versa) after a random time 1 CPU goes 100% and all calls are dropped.
