[OpenSIPS-Users] OpenSIPS Crashes

Hi Jorge,

It looks like the issue is in the SSL lib - if during the "tls_accept" 
something goes wrong and the accept fails, the cleaning procedure 
SSL_SESSION_free crashes - but all these are internal to SSL lib. The 
only thing that opensips itself can affect with is the memory manager 
(the libssl uses the opensips internal mem manager).

What I would suggest is to recompile your opensips with memory debugging 
support - maybe it can point to a double free or so.
What is your opensips version ?

Regards,
Bogdan
