[SR-Users] Kamailio 5.1.4 crashes

[Daniel-Constantin Mierla]

Hello,

the error message from dispatcher is not relevant for runtime, it is
saying that you have to set some parameters to dispatcher module (those
with avp names) because you use ds_next_dst()/ds_next_domain() --
without those parameters, you can't do re-routing using failure_route
and dispatcher functions.

>From the logs, it is nothing showing the cause of the issue, could be
your own modules or something else.

Try to generate a corefile and then get the backtrace with gdb. To
generate the corefile:

 - run "ulimit -c unlimited" in the terminal where you start kamailio
 - run kamailio as root user
 - reproduce the issue
 - there should be a log message saying that the "core was generated"
 - get the output of "bt full" from gdb inspecting the core file

Cheers,
Daniel
