[SR-Users] Multiple crashes of Kamailio 4.2.1

Hello Daniel,

 

There is no particular reason. It's just that our others Kamailio are
running 4.2.3. So, we try to have the same version on all nodes.

 

Regarding the backtrace, I'm surprised, because there was no manual
shutdown.

 

Unfortunately, for this occurrence of the crash, it's the only coredump
available. There was another crash later this day with two coredumps and the
following backtrace:

Objet : Re: [SR-Users] Multiple crashes of Kamailio 4.2.1

 

Hello,

there are newer releases in branch 4.2, was there any reason to stop at
4.2.3?

Back to the backtrace, this one is from shutdown, happening during the
cleanup, not showing the reason of the crash at runtime, unless there was a
manual shut down triggered at that moment. Do you have another core file? 

Cheers,
Daniel

We got some others crashes even after updated to 4.2.3.

Hello,

 

3 crashes occurred today (we never seen crashes on this server before)
during a period of 20 minutes.

 

I had a look to the coredumps. Here is a quick overview of the first entries
of "bt full":

I don't know how to proceed now. Can you help me to highlight the issue
here? Thank you.

Regards,

 

Igor.
