<p>Hello,</p>
<p>since it seems reproduces quite quickly, can you enable dumping
of the core file on crash?</p>
<p>Usually requires to run:</p>
<p>ulimit -c unlimited</p>
<p>echo "1" > /proc/sys/kernel/core_uses_pid</p>
<p>Then start kamailio as root user and wait for the crash, when
that happens, core files with name core.PID should be generated.
Grab backtrace with gdb from each of those core files, see some
additional details at:</p>
