Thanks for the reply. Here is the new output with the debugging symbols.

First, the simple backtrace:

Core was generated by `/usr/sbin/kamailio -P /var/run/kamailio.pid -m 64 -M 8 -u kamailio -g kamailio'.

Hello,

can you install the debugging symbols to get the lines that trigger the crash? Resend the gdb backtrace to investigate it. Also, the output for 'bt full' will be useful to see the values of variables.

Cheers, Daniel

Hello, this is the first time I send a question here, hope my english is good enough to explain my problem.

I have a Kamailio 4.1.8+RTPProxy setup working, but recently I saw RTP Engine proxy, so I decided to give a try. I installed the latest kamailio stable version (4.2.3) and adapt the configuration I have(that uses a MariaDB database), to try the rtpengine module, but I couldn't even start kamailio process, cause I received a segfault problem at unixodbc module. The version of unixodbc that I installed is 2.3.1-10

That was the first time I encounter this error. I thought that maybe the database I have created with the version 4.1.8 wasn't compatible, so I decided to create a new database, but the problem persisted.

So I'm here to know if someone know something about this, or have had a similar problem. I attached the system log for Kamailio, and a backtrace I made using "gdb" with the corefile that Kamailio creates when it crash.
