Les

The Truxton Load Status Monitor (Les) is a service that runs on the network that monitors the message bus and decides when media is ready to advance. There only needs to be one instance of Les running on the network, not on every machine. If there are multiple Les processes on the network, they will take a vote to see which process should be the Chosen One because there can be only one process in charge at a time.

If Les is not running somewhere, loads will not complete. They will get stuck at 48-60%.
