I have identical OS software running reock-solid on two other DL380 ProLiant servers, but they are G6 models, not G7. On the G7, the installation went perfectly and the machine ran great for about 2 weeks, when it just seemed to "stop". The system stopped responding on the network, and there was no video on the console (or remote console via iLO). It would not reboot or cold boot through iLO, I actually had to hold the power to turn it off and then hit it again to power up. >> > > OK everyone, here is an update: > > The server crashed again overnight.

I tried to load memtest86 from the CentOS 5.5 Install DVD, and the system immediately rebooted. I eventually loaded memtest86 from an OpenSUSE 11.4 install DVD I had laying around, and that ran OK. I ran memtest86+ starting Friday about 6 pm and stopping Monday morning at 10:45 am. Almost 70 full passes were completed, and no errors were found.
