From memory there is a setting in the key server software that you can set to cancel a user license once there machine has been idol for a certain period. Can't say exactly where the setting is as I don't have access to a server at the moment.
Some years ago we had the same problem with all licenses being used and not being released even after Archicad was shut down, but after I set this to 180 minutes we have never had the problem again.
180 minutes should be more than enough (for that long lunch break) and it is short enough so they will all reset overnight when not being used.
