[SR-Users] Re: TLS module crashes with FIPS OpenSSL

Hello, are you on openssl 3.x by any chance? If yes, please upgrade to kamailio 5.7.5 or 5.8.1 and set tls_thread_mode=2 in the kamailio.cfg, as it fixes certain memory corruption issues on this openssl version. If you are still getting crashes after the upgrade and setting, please let us know, it might be something related to the FIPS mode.
