How to Disable/Enable exacqVision Watchdog Timer

Description 

Built by Exacq “BBE” NVRs utilize a watchdog timer, which during normal operation is reset every second. If the watchdog timer has not been reset within 60 seconds it will trigger a system reboot. The assumption being that machine is in a bad state. For various troubleshooting reasons you may need to disable/enable the watchdog timer.

Disabling Watchdog for units with lack of Clarity in logs for Unexpected Errors.

IF you have a unit that is not clearly stating the reason why the unit is rebooting or getting random unexpected errors turn watchdog off to see if the unexpected errors go away and the unit remains running with no random reboots. I would enable debugging in the core/psfpi/sysmgmt/ in the client to gain the ability to get more detailed logs in case the unit remains rebooting randomly. This is not to be done if there are logs pointing to an issues.

Manually Triggering a Watchdog

Because of issues archiving over a WAN (see this article), it might be necessary to manually trigger a watchdog so that the server is able to start up successfully. To do this, complete the following steps:

  1. On the System configuration page, open the Watchdog Timers tab and make sure the motherboard watchdog is enabled.
  2. Open a Terminal window to the server.
  3. Execute ps -ef | grep core to find out the process ID of the core process. If multiple IDs are reported, use the lowest.
  4. Execute sudo kill -9 [pid], where [pid] is the process ID from the previous step.

The server should then restart within the specified watchdog timer timeout.
