System continues to crash, although we've had periods of 5-7 days when it does not crash. Have not been able to identify a pattern.
This customer sells vacuum cleaners and they take old vacuum cleaners in as trade-ins. The old vacuum cleaners and their new demo units are stored in the same room as system. This may be a dumb question, but is it possible that having that many electric motors that I assume have magnets in them create some kind of interference? They have someone who comes by from time to time to take away the old vacuums, which could explain why there are periods when the system doesn't crash.
Just a thought.
