WATCHDOGD(8)            FreeBSD 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
     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
     timeout.

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

     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.
