Thanks, that's helpful. Perl wasn't even on this server when this all started, so I've no idea what the systems guys even put on it. As I said in the original message, I don't actually have access to the box myself, which is frustrating matters.

For what it's worth, the error that the person running the script reported to me in email was: Unable to open input file UDB_sessions01252011

That leads me to believe that the code is failing at this point: 

## Open input file
open(INFILE, "$infile") || die "unable to open input file $infile\n";

The code as written is pretty darn elementary. I am assuming that my user got the name of the file she was trying to use correct, though I could double check that.
