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 ker- nel 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.
