I've access to a number of XServes running 10.8 and not seen the problem. I've seen the same and similar problems on other hardware and its usually a hard drive issue.
An idea of the drive configuration and quantity might help? For example is their a RAID card installed? If not are all the drive bays full? Is there a mixed make and capacity of drives? Are the drives configured as a software RAID? Anything attached externally? Tape drive etc?
Without any further details it's difficult to offer anything further.

The xServe has an Apple RAID card installed. Drives are all Western Digital 2TB RE4 drives purchased at the same time. The server has been working fine for most of the year but we have started having problems in the last 2-3 months.

RAID configuration is what? Have you checked the log in the RAID Utility? Do you have an external drive (firewire preferably) you can clone the current server OS to and boot from that instead? If you have the time and luxury to do the latter and run the server for a few days in that manner and the problem goes away then it's a problem with a drive or drives or a combination of the RAID card and drive or drives.
