from an evening's reading of my new "Inside Cisco IOS" book...
the watchdog will check to see whether a particular process is hogging the
CPU, and if so will kill it off (believe the default is 2 seconds).
Reckon that your router had got itself in such a state that that one of the
"core" processes had killed the CPU, the watchdog had killed it and hence
the reboot.
check out your logs (you do log stuff don't you?) - you may get some kind of
traceback log associated with this.... I have seen this with non-"core"
processes, but if the router has booted, then maybe not ;-)
