Hello Daniel,

Yes, I can reproduce it every time I run those commands from within the script.

I’ve only included the trace(see attachment) from the point kamailio crashed, since it only happens when a certain condition inside the script is met. (if statement)

But when the condition is met, it crashes every time.  

If you need more information, please let me know.

Regards,

Grant

Hello,

can you reproduce it every time you run those commands? Or is it happening from time to time?

If you can reproduce, set debug=3 and send all the logs to me. Also, it would be good to set 'ulimit -c unlimited' before starting kamailio to get a coredump which would be easier to troubleshoot.

Cheers,
Daniel

Hello,

Kamailio crashes when I try to execute the following jsonrpc_exec functions:

jsonrpc_exec('{"jsonrpc": "2.0", "method": "domain.reload", "id": 0}'); #domain module

jsonrpc_exec('{"jsonrpc": "2.0", "method": "addressReload", "id": 0}'); #permissions module

This one works fine:

jsonrpc_exec('{"jsonrpc": "2.0", "method": "htable.reload", "params": ["tablename"], "id": 0}');

Any ideas?

Running on Debian 7.8 and Kamailio 4.2.3.
