Umount / mnt

I have a perl script that mounts and smb share then umounts it at the end. A simple system "umount /mnt/backup".
About 60% of the time it will hang and suck up about 98% of the cpu taking 10-15 minutes to complete. Other times it completes right away. This is on a test server with nothing else running at the same time.

I have tried it back to back with it working then not working then not working then working... You get idea.

Suggestions?
