Hey, I've had a look and can't see anything obvious. Two things however you could investigate, it seems there is some crash informaiton available. Are you able to provide this?
Crash Information
-----------------
Crash information is available; use 'show ap debug crash-info' to retrieve
--------------------------------------------------------------------------
Secondonly, it is possible the logs prior to the warm reset are being overwritten then the warm reset occurs. I can see that there is no syslog configured to capture these logs. Are you able to configure a syslog and then provide any logs once the next-warm reset has occured?
