These messages are benign and shouldn't have any effect on the call.

Ok fair enough. I was worried that it had something to do with the AS5350

going unresponsive. My associate rebooted the device before I could get a sh tech or some log messages. the device went awol yesterday. the device was completely offline. Ethernet was down and no calls being sent. Unfortunately I dont know if it was just something as simple as a switchport failure, cable failure, or perhaps a problem in IOS somewhere that would cause the device to hose up.

Would the show tech show anything after the device was back online? I cant really interpret all the info it provides.

the device is working fine today but unfortunately w dont know what happened. Im watching the logs cloely today to see if I can  catch it next time.

Show tech when all is ok most likely will most likely not provide much useful info.

You can alway run it through "Output Interpreter" on to help:
