Dear Guru,
I have a perl script that "usually" works well. It is executed in this way.The code prints to STDOUT: 
$ perl mycode.pl input_file.txt > output.txt

[download]
Now one time when it take certain file (smaller than usual one), my code above just "hang in there". It doesn't die off and not giving segfault message or any error message as per normal error message we encounter.

My question is what's is the best way to debug find out the cause of this hanging problem?
