(spelling fix) It should now be much better.

But this should not be much better. Just to double check, you set the core parameter tls_thread_mode to 2? You can also try to update to 6.1.3, just to verify that it was not fixed already. If you have a core dump, you can create an issue with the backtrace. https://www.kamailio.org/wikidocs/tutorials/troubleshooting/coredumpfile/ Cheers, Henning From: Mody, Darshan via sr-dev <[email protected]<mailto:[email protected]>> Sent: Montag, 15.

We have encountered core dumps and identified heap corruption during debugging. The issue appears to be related to conflicts between ser_free and OpenSSL context free (SSL_CTX_free). Has anyone else experienced similar issues with this configuration? Warm Regards, Darshan
