 fuser /mount_point_directory

gives the pid of the process accessing anything under that directory

 ps l pid

will give info on the what that process is.

Then use close the offending program - or kill it

 fuser -ik /mount_point_directory

kill all processes (with a query) accessing that directory -
use with care :-) Just use -k if you are feeling brave. The fuser manual
page has more info.
