CommandException: return code: 3

I am converting .tif images to .jpeg format and getting the following exception for several images:

org.im4java.utils.BatchConverter$ConvertException: org.im4java.core.CommandException: return code: 3

What does return code: 3 mean? I hope someone can help me.

I would check to see if the error code comes from the org.im4java.utils.BatchConverter code
