X10G security blade system watchdog

X10G security blades implement a system watchdog daemon to monitor critical system processes and conditions. Should one of the monitored processes or conditions fail or fault, the watchdog service performs a reset or restart.

Monitored processes and states include:

Appliance kernel -- is the kernel active.

Domain Agent -- is the Domain Agent running. This is an essential process that is responsible for communicating between the user interface and a security blade's back-end processes.

Journal Commit I/O -- detect a "journal commit I/O" error.

File table -- detect a file table overflow condition.
