Please post your OS and version, the scripting language, and how you are starting the script (since you state it's working in testing and then immediately state it's getting an error ) both in testing and when it's getting an error.

Also post the script (if possible) - this will assist the folks who can help you.

The only info I found on the error was here but I can't tell if that will help you or not.
