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.
