Question

what does this mean ?

Answer 1

After watchdog starts, it puts itself into the background and then tries all checks specified in its configuration file in turn. Between each two tests it will write to the kernel device to prevent a reset. After finishing all tests watchdog goes to sleep for some time. The kernel drivers expects a write to the watchdog device every minute. Otherwise the system will be reset. As a default watchdog will sleep for only 10 seconds so it triggers the device early enough.
