Hello,
I got two more crashes but they seem to be different.
The logs mentioned:
kernel: kamailio[27096] general protection ip:7f0b3e0bae55 sp:7fffdbce5fd0
error:0 in dialog.so[7f0b3e077000+8f000]

Both gdb are related to dialog module:

Objet : RE: [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:

Igor.

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
