[SR-Users] jsonrpc_exec crashes kamailio

[Daniel-Constantin Mierla]

Hello,

I need the logs printed by kamailio before the crash, to see what was
processing at that time. After crash is no information in the logs
printed by itself why it crashed .

The traces printed in syslog by the kernel are not easy to use for
troubleshooting and I see the core was not generated to use gdb for a
proper backtrace. Have you run 'ulimit -c unlimited'?

Cheers,
Daniel
