samba - Mar 2001 - IPC shared memory problem

I am running Linux Kernel 2.2.18 which is upgraded from from RedHat 6.2
kernel 2.2.14 using standard kernel patches from kernel.org.  I am running
Samba 2.0.7 from RedHAT 6.2 upgrade/addendums.  

When I get more then one connection smbd will die and log.smb will read this

- [2001/03/23 06:12:19, 0] locking/shmem_sysv.c:sysv_shm_open(667)
-  Can't create or use IPC area. Error was File exists
- [2001/03/23 06:12:20, 0] locking/locking.c:locking_init(174)
-  ERROR: Failed to initialise share modes 

I have gone through the archive on this mailing list and have seen quite a
few people with this problem which would lead me to believe that there
should be a solution for it in a FAQ somewhere but I can't find anything at
all on that subject.  If anyone has a solution to this problem that doesn't
deal with having patched the kernel, or running Mandrake please post it
because I am pulling my hair out.

We've started having these intermittent problems with our samba 2.0.6
installation. About a dozen people on WinNT client machines are using a
Dell file server, running Redhat 6.2. They installation has been purring
along with no problems for about six months. About two weeks ago, we
started finding that some people, when the log into their NT boxes, are
mapping some shares, but not others. Other people are having no problems
mapping their shares at certain times, yet experiencing problems at
other times. People are sometimes mapping some shares that they do not
map at other times. The log.smb shows many "Gethostbyaddr failed" and
"Denied connection." We have not made any changes to our samba files
on
the Linux box. Can anyone suggest where I should start looking to figure
out why this is suddenly happening?

Hi Craig,
Try the following; bring down samba, then use ipcrm  to remove the shared
memory
and semaphores associated with it.
Then log in as root (don' su to root, actually LOG IN as root), and start
samba again.
I have seen similar problems when someone started samba after su'ing to root
from a 
normal user...
Hope this helps,
Don
