If you want this to stop, as it sounds like a very inconvenient time for a Stop in Play, then change the Core to a Fixed IP Address using the Sooloos Configuration Program

I had the same problem of the Core Resetting itself at the same time every day and setting the IP Address of the Core to Fixed IP resolved the problem

And I'm not that sure that this has anything to do with any System Checks that Meridian may be doing!!
