I've been trying to move a SQLite database into a MS SQL database for one project. Somehow now, all my tags on all my projects are disconnecting and reading "unknown last value". I've checked lots of places in my gateway and can't find anything particular.

My tags will come back only for about 3 minutes after I restart the gateway using gwcmd. Does anybody have an idea what's going on?

Thanks.
