I did go ahead and reboot.  WAAAAAA.  

I tried a script that was:
umount /mnt/smb/baiscan 
mount /mnt/smb/baiscan

and no luck.

I did however not verify that it got to the second line there which was the
mount.

To prevent this from happening again I will probably put the files of interest
on a different server and access it from the win machine through smb and the ap
server through nfs.

If it happens again I will run a strace and try the proc stuff.
