Xserve G4 stability (random processes crashing)

[Kevin Day]

Thanks to some help, we've got 8.0-STABLE running on several Xserve G4 boxes now, in both UP and SMP configurations.

However, all of them are showing weird stability problems. Running OS X Server, they were completely stable for years doing pretty hard work (video encoding) with no errors. They all pass Apple's hardware burn-in, too. But, doing a "buildworld" or "buildkernel" will result in random segfaults, invalid .o files being created, or ICEs that go away after immediately retrying. (i.e. it doesn't appear to be data from the disks being cached incorrectly, I don't have to force a re-read to fix) Pure CPU tasks (like memtester from ports) work fine for days. 

Are there any known issues with 8.0 on an XServe G4?
