It would help if you told us what the program IS, what it does, etc. Can't guess as to what it's doing when we don't know, and you don't provide any useful information.

If this is something you wrote, tell us what it does, and post the relevant portions of the code. Tell us what process(es) it starts, and what it's trying to do. Could be it's just detecting a stale lock or PID file...

What TB0ne said ...

On top of that, if you CAN'T see any perl process running yet the
"program" complains that it's already running ... there's always a
chance that it maintains status via some file, and that the file
didn't get removed when the program went away (e.g., it was kill9ed
and didn't get a chance to clean up).


Cheers,
Tink
