 Could it be that there is a problem with your shell?
 For successful completion, "$?" should contain the
 value 0, not an empty string.  This looks fishy.
 
 One possibility is that your shell is malfunctioning
 because of a resource shortage and insufficient error
 checking.  But that's just a wild guess.
 
 Please use plain /bin/sh to make sure that the shell
 is not causing (or hiding) any problems.  If you still
 get exactly the same results, something really strange
 must be going on.
 
 By the way, I noticed that your machine (2.3 GHz Xeon)
 has only 320 MB RAM, which isn't exactly plenty,
 depending on the things that are running (you mentioned
 "heavy usage").  Could it be that you're running out
 of memory?  (Although the symptoms aren't typical.)
 
 Best regards
    Oliver
