Watchdog not fed

When using driver station we are able to connect to robot and drive sporadically, but have a watchdog not fed meesage. What is this and does it have anything to do with the DS being so sporadic?
Also we have an ERROR Code 44015.

There are some Watchdog oddities related to the Driver station that National Instruments is working on.
See the Watchdog thread and post what you see happening with the Watchdog there. NI is more likely to see it.

An error 44015 means there’s an error or typo in one of the RefNum’s you are using. The ones when you Open a device in and then later use in in
