Well, before panicing, I'd start by using dpkg to verify all the files in
the package that provides the 'sleep' binary. Chances are, it's become
corrupt, somehow (do you put mostly-quiescent files on the same partition as
frequently rewritten files, like /var/log/* ?)

If the verify fails, try reinstalling that package. It might also be wise to
do a full system verify to uncover any other potential nasties that might be
waiting for you to find at an even more inconvenient time!

Only if such steps fail would I consider doing a clean OS reinstall. And
only if /that/ failed would I start suspecting hardware.
