This machine was a "ghost ship." It's use had long come and gone and people had moved their stuff off onto new machines. It was running 32bit RHEL 5.5 no patches, no nothing. It was a security risk at this point. To Mike's point, unless there's good change control, you run the danger of having a machine that's not ever going to reboot sensibly.
A couple years ago I stumbled upon a linux box that was running an ancient version of mysql.. the database was up, but it was running out of a directory like /u01/mysql/bin
The disk /u01 was LONG gone.. but the database continued to run.. it's data was being written off on to a different disk and things worked.. but it was clear that machine would never had rebooted.
