WATCHDOGD(8)		  BSD System Manager's Manual		  WATCHDOGD(8)

NAME
     watchdogd -- Software watchdog daemon

SYNOPSIS
     watchdogd [-d] [-I	file]

DESCRIPTION
     The watchdogd utility interfaces with the kernel's	software watchdog fa-
     cility to ensure that the system is in a working state.  If watchdogd is
     unable to interface with the kernel over a	specific timeout, the kernel
     will take actions to assist in debugging or restarting the	computer.

     One possible circumstance which will cause	a watchdog timeout is an in-
     terrupt storm.  If	this occurs, watchdogd will no longer execute and thus
     the kernel's watchdog routines will take action after a configurable
     timeout.

     Upon receiving the	SIGTERM	or SIGINT signals, watchdogd will first	in-
     struct the	kernel to no longer perform watchdog checks and	then will ter-
     minate.

     The watchdogd utility recognizes the following runtime options:

     -I	file  Write the	process	id of the watchdogd utility in the specified
	      file.

     -d	      Don't fork.  When	this option is specified, watchdogd will not
	      fork into	the background at startup.
