You can find out if the issue is in opus or not by looking at the backtrace of the core file.

Hi,
 
Is anyone aware of an issue with implementing the opus codec on freeswitch?
 
We have recently implemented opus and ever since the switch has crashed every hour or so.
 
The logs show nothing around the time of the crash so I am thinking it is deep in the opus module.
 
We are running the latest stable version 1.2.23.
 
Any help you could offer would be appreciated.
 
Regards
 
Chris
