Hello Daniel,

Thanks for you reply.

I checked again and I am using the version 5.0.4 from the debian packages for debian (bellow there is the output of some commands to confirm this).

I also reboot the machine, but i still have the same problem with the same output on gdb.

Best Regards,
Jose Lopes

Hello,

are you sure that kamcmd was compiled with the 5.0.4 version? In branch 5.0, at kamcmd.c line 591 is a line with just a curly brace, then one starting the send_binrpc_cmd function, so that's not a line that can cause a segfault.

Cheers,
Daniel

Hello,

I invoke kamcmd inside Freeswitch Lua Scripts and right now i am getting segmentation fault any time.

This started to happen after I upgraded kamailio from 4.4 to 5.0.4 .

I tried to analyse the core dump and it give me the next information.

When I execute on the console, the command works.

Am I doing something wrong?

There is any alternative or better way to communicate with kamailio?

Thanks in advance

Best regards,

Jose Lopes
