Router Crashes
When we refer to a "system crash", we mean a situation where the system has detected an unrecoverable
error and has restarted itself. A crash can be caused by software problems, hardware problems, or both.
This section deals with hardware-caused crashes and crashes that are software-related, but may be
mistaken for hardware problems.
Important: If the router is reloaded after the crash (for example, through a power-cycle or the reload
command), important information about the crash will be lost, so try to collect show technical-support
and show log output, as well as the crashinfo file (if possible) before reloading the router!

Watchdog Timeouts
Cisco processors have timers that guard against certain types of system hangs. The CPU periodically
resets a watchdog timer. The watchdog timer basically controls the time of each process. If the timer is
not reset, a trap occurs. If a process is longer than it should be, the watchdog timer is used to escape
from this process.
