I have three identical HP Proliant servers. All three are identical in hardware.
I was having a problem getting Remote Desktop to work on these three, plus, they were all hanging quite often. So, I made a disk image that I had on a working server, and I installed that image on these three HP servers.
Worked for about two weeks. Now, they hang again. When they hang, the screen is blank, the keyboard and the mouse don't function, and only a hard reboot fixes it.
I work for a radio station. These servers are running TeamSpeak. We use it for remote broadcasts. That, and Gnome, is the only thing these machines run.
CPU usage is 67%...with Teamspeak using 30%.
Here are the logs (both /var/log/messages and /var/log/syslog) for around the times the machines crash (all three appear to lock up at the same time.

Any ideas what's causing these machines to hang at the same time?
