Hi Craig,
Try the following; bring down samba, then use ipcrm  to remove the shared
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,

Subject: 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.
