umount in shell script

[George Vanev]

Hi all,
I have the following script:


#!/bin/sh
mnt_path='//user at server1/archive'
mnt_ip='xxx.xxx.xxx.xxx'

mkdir /usr/tmp_mnt
mount_smbfs -N -I $mnt_ip $mnt_path /usr/tmp_mnt

#rotate files
#dump mysql database
#gzip
#encrypt
#copy to /usr/tmp_mnt

umount /usr/tmp_mnt
<EOF>

Sometimes /usr/tmp_mnt is still mounted.
It's random behavior.
I didn't noticed any logic when it is unmounted or not.
OS:  FreeBSD 6.2-RELEASE

Thank you!
