Analysis:
=========
==> Log shows that active supervisor didnt get right keepalive packet from standby sup at a result it reload standby sup. It looks like during the timeframe mentioned above -there has been a communication issue with the statndby like some from of IPC communication is blocked . I think this is either a stuck port on the RP of a Standby -module.
==> Going forward I would like to know if we can do reseat of the standby module? If not then monitor for now and get back to me in case if this issue re-occurs.
Also kindly check if there is any crash file been generated for this standby sup on the box?
HTH
