I think I may have found the problem, and I may have caused it......
All our jobs come through a web browser type set up, similar to say a taxi service I guess and I added a google chrome extension to refresh the page every 10 seconds, this pc is displayed on a large tv in the main area of the office, the TV is turned on and off but the pc runs 24hours for convenience (simplify for idiots to just have to turn on/off a tv at the start of the day and end)
Im guessing those page refreshes must add up, just trying to work out the bytes of a page refresh and then every 10 secs for 24hours a day...... FML
