At first I thought it was because we were allowing students to bring their own devices putting a heavy load on our older Astaro 110/120 hardware. But I've just noticed strange stuff going on with the Astaro's RAM and CPU usage.
For whatever reason, even when no one is here, the RAM always hovers at about 75%. The only machines that are even on overnight are the server and one admin machine we remote into.
Also, we have these CPU spikes that shoot from 4% to 100%. I would think that was just peak stuff like when classes begin, but that kind of thing happens in the middle of the night also.

We talked to the company that sold us the box, and they said we needed to upgrade and charged us $80 for the "assesment". The box just has 1GB of RAM, but it was running just fine until recently. And runs just fine most of the time besides these random blackouts that happen about once a day or so.
Any ideas?
