Over 30 years ago I worked for a company that supplied minicomputer systems for pathology labs in hospitals. I was on-site at one location, where the customer had complained of the system continually restarting itself.
I was staring blankly at the machine, wondering where to start, when there was a "whump!" that was felt rather than heard, and the lights flickered.
"What was that?", I said.
"Oh, just the X-ray department next door".
Problem found!
In an existence before that, we used to have similar problems on our micro development kit. We noticed that they got more frequent around 5pm. We eventually realised that it was due to the lift in the building.
