Joshua C. Colp commented on ASTERISK-28510:
-------------------------------------------

16.5.0 uses a different method of doing packets with DTLS, so it would exercise new code in OpenSSL and could hit a bug within it.

> We have observed several occurences of Asterisk crashing after recently changing our dial-plan to PJSIP. 
> We've not found any direct way to reproduce the problem, but it does seem to be restricted to high trafic hours - however there doesn't seem to be any particular threshold that causes the crash.
> For every occurence we've observed the following entries occur in the log immediately prior to the crash.
