Watchdog processes are those which monitor the activity of another process, and are very common in communications devices. Often, if it appears that the monitored process has gotten stuck in an endless loop or is otherwise not behaving properly, the watchdog process is empowered to restart the other process. 

There's not enough details here to speculate what is happening. If this only happened once or twice, ignore it. If it's repetitive, contact your reseller or aerohive support for troubleshooting assistance. They will want to know the device model, the version of code on it, whether it ever worked properly for you, what has changed recently, etc.
