[SR-Users] Kamailio segfault 5.4.4

[Daniel-Constantin Mierla]

Hello,

since it seems reproduces quite quickly, can you enable dumping of the
core file on crash?

Usually  requires to run:

ulimit -c unlimited

echo "1" > /proc/sys/kernel/core_uses_pid

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:

Cheers,
Daniel
