Dmitriy Serov commented on ASTERISK-25744:
------------------------------------------

This error was before, but much less frequently. But it is difficult to say, because the server kept falling over for a different reason: ASTERISK-25439
After eliminating one of the causes started to fall with TLS.
Most likely this error is a consequence, a manifestation of some other situation.

I'm ready to put in the right place assert in order to catch the situation earlier. For example, I don't understand how in backtraces can be such an IP address (despite the fact that the length of the value 12 bytes):
