Richard Mudgett commented on ASTERISK-26686:
--------------------------------------------

Thread 70 and 71 are deadlocked.  The locks involved are the pjproject transport manager group lock and the monitored_transports container lock.  The deadlocking code is still present in 13.21.0 even though that code moved to a new file.
