Asterisk 13 problem call processing

[danial]

I 'm running Asterisk 13.30 ( Freepbx distro version ) on a VM server :
CPU : 8 cores
RAM: 16GB
The server often works properly but sometimes asterisk stop the call processing with this error :

in this situation, “asterisk -r” command does not respond and just show bash prompt.

no core dump file generated .howto getting a backtrace or find the cause of the problem in this state?
