Joshua Colp commented on ASTERISK-26686:
----------------------------------------

This has nothing to do with astdb. It's a lock inversion in the PJSIP transport management code we have for keeping transports alive. One thread has our lock and is trying to get a transport lock, another thread has the transport lock and is trying to get our lock.

> Asterisk locks with no further processing. This looks to be related to the ASTDB holding a lock.
