Been there ... done that
But the problem was that we kept loosing data! Machine was working fine, the days statistics printed off, but next morning they were missing.
After several days of the same problem I went on site to monitor things. A bit longer run to get to site. Daily stats run off everything fine. The machine was left on so it was still accessible remotely to allow managers to check anything they needed, and shut down later to restart in the morning.
7PM a hand appears around the corner, pulls out the plug and plugs in another plug - without even looking - then the vacuum starts ...
The real irritation here was not so much the hand of god, but the fact that while 'write to disk' was activated on the machine it turned out it only happened when the program shut down! Fixing that fault help a solve other site problems where electricity was an equally mystic provision.
