"Wipe Free Space" wants to turn itself off

I run "wipe free space", but when I come back to check on it in about 30 minutes it is giving me the message that says something like "do you really want to discontinue wipe free space"? If I wait for about 2 hours to check on it, it will have turned itself off. How can I fix this? Thanks.

Please don't double post.
