Try 'lsof' to see what processes are using what files.  I've not
tried it on a windows share, so YMMV, but it's the best tool
(available on FreeBSD which seems to lack 'fuser') that I've found
for other such difficulties in umounting various unix-served
filesystems.  Sometimes one might start a new process (i.e., an
xterm) when within a mounted filesystem then even leaving that
filesystem will not be sufficient to allow a umount (in my
experiance at any rate.)  Such things can be confusing and
difficult to track down.

'lsof' (combine with 'grep' and 'wc') is also good at determining
that it is 'mozilla' which has opened 10,000 file descriptors over
the last three days too ;)

BTW, 'lsof' is not part of the base system I don't think.  In the
ports collection, it's in sysutils/lsof/.

Thanks,
