I believe I have a server with faulty hardware. I think it's the motherboard, because I've tested the RAM, but anyway, I'll explain what happens...
Every night between 1am and 5am, Exchange performs online maintenance on its exchange stores. The problem is that every night, while one of these maintenance procedures is executing... the server freezes/locks up. When I get to work and check on the server, the server doesn't respond and screen is just locked on a stuck screensaver.
I've only figured out why it is freezing because I logged on at 1am and watched taskmgr and saw that a particular process was chewing through a lot of ram, and then just suddenly I lose connection to the server. It turns out to be exchange.
So my question is.. what does exchange do while in this maintenance period? I thought it was basically just a defrag. Which, if that is the case, I might have to move the exchange database to another computer and perform an offline defrag every month or something.
If you give this server a mammoth task to do.. involving a lot of memory.. it freezes. HP don't think anything is wrong with it after their remote testing and don't want anything to do with it. I'm raging.
Any thoughts or suggestions would be greatly appreciated.
