Description

We updated one of our endpoint facing proxies last night, from 5.7.4 to 5.8.2. After running for about 12 hours, it crashed. It had about 1.8k TLS connections at the time of the crash.

When crashing, Kamailio produced core dumps of two processes. One of them must be the TCP listener, the other maybe the main process.
