Open Stack

Thanks for the ideas! They are cheap clone servers using Intel® Server
Board S5520HC with 48Gb of RAM.

-The nodes simply reboot, without any interesting logs. Not all at the same
time.

-There's no automatic updates or anything like it.

-I don't think overheating is the problem, because they reboot early in the
morning when they have no load at all. They usually reboot around 03:00 to
05:00 AM.

I had no idea about this bmc thing Ill check it out.
