I have a Dual G4 Xserve running 10.4.11 and I've been experiencing frequent Kernel panics. I've been unable to determine the cause and I've run out of ideas and options.
Warranty support is of course long since expired.
The internal CD-ROM drive is broken so I've been trying to use an external DVD/CD-ROM drive to boot off the Apple Hardware Test CD, but that doesn't work either. I downloaded the AHT image for Xserve from Apple and it comes up as an option when I reboot holding the Option key, but when I select the Hardware test disc and click the Enter key the boot options refresh and I'm not able to boot off the CD.
I was running 10.4.9 at the time when the kernel panics started so I upgraded to 10.4.11 thinking it might help, but it didn't.
There is no regular interval between kernel panics. I've experienced the server simply crashing and rebooting on its own, error logging directly on the screen over the desktop and a gray screen saying "Please reboot your machine."
It would seem that my last option would be to re-install OS X Server.
Here are the latest panics from the panic.log:
