samba - Mar 2003 - smbcontol smbd close-share doesn't close all open file handles.

I have a client connected to a share CocaCola:

smbstatus shows:

CocaCola     root     root      2959   tdickson (10.73.0.109) Wed Mar 26
13:16:16 2003
IPC$         root     root      2959   tdickson (10.73.0.109) Wed Mar 26
13:16:09 2003
IPC$         nobody   nobody    2959   tdickson (10.73.0.109) Wed Mar 26
13:16:15 2003

"lsof | grep CocaCola" shows:

smbd      2959 root   22r   DIR       58,0    4096       135
/mnt/H29/CocaCola
smbd      2959 root   24r   DIR       58,0    4096       135
/mnt/H29/CocaCola

after running (as root)

smbcontrol smbd close-share CocaCola

smbstatus shows:

IPC$         root     root      2959   tdickson (10.73.0.109) Wed Mar 26
13:16:09 2003

(cocacola has been closed and is gone)

BUT, lsof |grep CocaCola still shows the smbd process having the directory
open:

smbd      2959 root   22r   DIR       58,0    4096       135
/mnt/H29/CocaCola
smbd      2959 root   24r   DIR       58,0    4096       135
/mnt/H29/CocaCola

Is there anyway to kick smbd so that it will correctly close the open files
in a certain directory? I want to unmount the snapshot, but can't do it
while there are files open. I can stop smb, and then unmount, and then
start, but that interrupts access to other shares.

(As an aside, it seems that having ACLs enabled may be part of the issue. On
another test machine, it works correctly, but that machine doesn't have
ACLs).

Any work-arounds would be appreciated.

Thank you
