For those that have had to do the Scan almost all the time now - I was able to find away to "fix" this. Seems when you have a backup service or something else on like that one the server that has the database files - the connections on the services get paused by Windows or stopped while still saying running. Try this script I wrote:

I've had almost no calls from clients since doing this "fix".
