How long was the off/on cycle? If it was short it would be reasonable to do it periodically. I don't think one can pin the blame on the vendor alone.

Clearly the vendor thought it would be reasonable. They failed at communicating it, though. Putting a number on it would have made things clear: “The system must be rebooted after at most 12 hours [or whatever the appropriate value would be] of operation.”
