At USC we have had the same symptoms.  We originally thought it was a 
hardware issue and replaced a harddrive and controller card because we 
saw I/O errors.  We still get this problem from time to time and the 
only way to correct it is to power the computer down and backup again. 
 Now our logs show nothing but it will still hang.  Today the machine 
hung and would not display the webpage.  When I tried to look at the 
processes running it would hang on the request.
