The log messages indicate that a core file was generated:
```
May 3 20:18:20 lwm-PowerEdge-R720 /usr/local/sbin/kamailio[46694]: ALERT: [main.c:727]:
handle_sigs(): child process 46727 exited by a signal 11
May 3 20:18:20 lwm-PowerEdge-R720 /usr/local/sbin/kamailio[46694]: ALERT: [main.c:730]:
handle_sigs(): core was generated
```
Can you locate it and get the output of `bt full` from `gdb` investigating the core? The
corefile may be either in `/` (root folder), the runtime directory for kamailio or a
special folder configured in the OS for dumping the core files.

It seems that the core of the process that crashed was overwritten at shutdown. Can you
enable core file per pid with the next command:
```
echo "1" > /proc/sys/kernel/core_uses_pid
```
Then reproduce the case. You should get more core files, each with the pid number in the
name. Take the bt for every core file and paste them here.

Somehow this went on the side, but I just pushed a patch that hopefully takes care of it.
On the other hand, I think janssonrpcc might be a better alternative -- iirc, it was added
by the same developer as jsonrpcc, targeting to be a better replacement for jsonrpcc.
