CIFS mounts will cause stalls on shutdown

Question

I've had this problem for awhile, but I've been brushing it under the rug.  I have several mount points set up so that I can access several different webspaces locally.  They are all set up so that they need to be manually mounted(I don't need them at every mount).  I have some mount problems..but thats not my main issue..talk about them laer..  My main concern is that when I try to shut down my system, it stalls upon trying to unmount these filesystems.  I am unable to umount them on my own..but not at shutdown.  I think the problem lies in the area of the order of unmounting.    I just ran across that idea, so I'll report back my findings tomorrow, but does anyone have any idea what would cause this kind of problem?

I had this problem, for those googlers here is the solution, post this into your /etc/rc.local.shutdown file:
echo "Unmounting samba-cifs filesystems..."
MOUNTED_CIFS_DIRS=`mount -t cifs| cut -d\ -f3`
MOUNTED_DIRS_ARRAY=($MOUNTED_CIFS_DIRS)
for i in ${!MOUNTED_DIRS_ARRAY[@]}
do
umount -l ${MOUNTED_DIRS_ARRAY[i]}
done
so that it looks like this:
[jam@ikaros ~]$ cat /etc/rc.local.shutdown
#!/bin/bash
# /etc/rc.local.shutdown: Local shutdown script.
echo "Unmounting samba-cifs filesystems..."
MOUNTED_CIFS_DIRS=`mount -t cifs| cut -d\ -f3`
MOUNTED_DIRS_ARRAY=($MOUNTED_CIFS_DIRS)
for i in ${!MOUNTED_DIRS_ARRAY[@]}
do
umount -l ${MOUNTED_DIRS_ARRAY[i]}
done
[jam@ikaros ~]$
this will unmount the cifs mounts before the network goes down. Thanks.
