NAME    [Toc]    [Back]

     watchdogd -- Software watchdog daemon

SYNOPSIS    [Toc]    [Back]

     watchdogd [-d] [-I file]

DESCRIPTION    [Toc]    [Back]

     The watchdogd utility interfaces with the kernel's software watchdog
     facility 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
     interrupt storm.  If this occurs, watchdogd will no longer execute and
     thus the kernel's watchdog routines will take action after a configurable

     Upon receiving the SIGTERM or SIGINT signals, watchdogd will first
     instruct the kernel to no longer perform watchdog checks and then will

     The watchdogd utility recognizes the following runtime options:

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

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