This is why I actually like rebooting servers every so often, 
preferably in a controlled fashion when you have some available down 
time. Things crop up at reboot that you had forgot about, or put off, 
or didn't know about in the first place, when you reboot a server. The 
longer you go between rebooting a server the less likely you are to 
remember what you had to do to fix it the last time :).
