I have a Dell Dual Core Server Running Fedora Core 8 220.127.116.11-27.fc8
This machine is a Samba Server as well as a VMware server to a Windows2003 server guest OS and another development machine. I recently experienced two disappointing events with this machine. The first time, about 3 weeks ago, the system just hung. It didn't respond to pings or anything. The guest OSs were also dead.
The second event happened last night, when the host just rebooted itself for no apparent reason. I checked /var/log/messages, and there was nothing in there to indicate the system went down. It's like someone pulled the plug. Only, in this case, the server is on a UPS. There are other devices attached to the same UPS and they did not go down.
Any suggestions would be greatly appreciated!
