jhanna has asked for the wisdom of the Perl Monks concerning the following question:
I have a script that runs perfectly for a long while and then dies mysteriously. I've included a lot of debugging print statements, but they haven't been able to isolate the problem. The script runs in a batch file (from a DOS command prompt) that restarts the script when it ends, and most of the time the batch file restarts the script, but sometimes the entire DOS box disappears. There's nothing pertinent in Window's event log. If there is an error on the screen, it's gone by the time I get to it. It runs between 6 and 30 hours between crashes, so I can't just sit and watch it.
What more can I do (besides putting a print statement after every line) to try to isolate the problem?
