samba - Oct 1999 - Root did not create the semaphore

Hello all,
I have a very annoying situation (at least at my end).  I set up Samba
2.0.5 on a Digital UNIX 4.0F system sitting on a Compaq DS20 server with
great success.... until recently.  I set up three directory file shares
with no problems, when I tried to set up a forth, quite a while after
setting up the inital three, I tried to access it from a NT box, I got
the message server not found, but the other three were still
accessible.  Before rolling the server into production, I applied the
latest patches, did some virtual memory tuning and rebooted.  When the
system came up, I started the Samba Server and gave the thumbs up.  The
next day, I was confronted with users not being able to access ANY of
the shares.  I checked to see if the processes were running, and they
were,  then I ran smbstatus and recieved the messages:

ERROR:Root did not create the semaphore
ERROR:Failed to initialize share modes
Can't initialize shared memory - exiting

So I did some more kernel tuning, and even reverted back to the settings
when samba did work with no luck.  Although I can see smbd and nmbd
running in my process lists, SWAT only shows that nmbd is running.

Any help?  The best guess I have is that my kernel's shared memory and
semaphore settings are not high enough, although I did try to double all
the values with no success.

Thank You.

we've fixed this for 2.0.6

I had this problem on a SCO box. 
Rebooting the server allowed samba to start properly.  

(I had been playing with 2.0.3 on the box, after that 2.0.5a
wouldn't start properly.  Maybe 2.0.3 wasn't releasing something ?)

Hello,
I am new to samba and need assistance for the error below.  The daemons
started fine (via script) but can't map drive and get error below.
Thanks for any help.
