I am getting SIGFAULT with this error,
Sep 22 15:37:21 rtsip-service: CRITICAL:core:qm_free: freeing already freed pointer, first free: usr_avp.c: destroy_avp(369) - aborting
Sep 22 15:37:21 rtsip-service: NOTICE:presence:destroy: destroy module ...
This is happening on a production machine where core dump is disabled. I have enabled core dump just in case it crashes again.
