[SR-Users] Kamailio crashing after comparing AVP with string

[Daniel-Constantin Mierla]

Hello,

reproduce the case with 'ulimit -c unlimited' executed in the terminal
before starting kamailio. You should get a corefile and then get the
output of 'bt full' in the gdb (gdb /path/to/kamailio
/path/to/corefile). Send the output here to investigate it.

Cheers,
Daniel
