Hi Daniel,

Thanks for your reply.

- what is the ssl lib version?

OpenSSL 0.9.8o

- it is happening all the time you try?

as soon as the phone send package on port 5061 the server crashes.

openssl s_client -debug -connect HOSTNAME:5061 -tls1
crashes Kamailio as well.

- what are the log messages printed in syslog before the crash?

/opt/kamailio/sbin/kamailio[30278]: ALERT: <core> [main.c:785]: child process 30293 exited by a signal 11
/opt/kamailio/sbin/kamailio[30278]: ALERT: <core> [main.c:788]: core was not generated
/opt/kamailio/sbin/kamailio[30278]: INFO: <core> [main.c:800]: INFO: terminating due to SIGCHLD

- can you enable core dumping per process, just to be sure this core is not caused by a kill or children processes?

Can you please advise how I can do that?

Can you try with the default configuration file? Kamailio comes with tls support you just have to enable it -- in kamailio.cfg just add after the first line:

#!define WITH_TLS

I tried and the result is the same.

I just added:
listen=tls:IP.ADDRESS:5061

I am trying to isolate the situation and the cause of the issue. Few hours ago I used tls on ubuntu 12.04 and all went fine.

I think of trying on the newer OS in the evening.

Thanks,
Den

Cheers,
Daniel

I am using kamailio-3.3.2 on Ubuntu 11.04 x64 and when trying to connect via TLS from my Yealink phone kamailio crashes with the following backtrace:

The manual I am following is http://www.kamailio.org/dokuwiki/doku.php/tls:create-certificates
