Can anyone help/explain why the NMBD process on my VMS server is crashing, I

VMS 7.3-2, with TCP 5.4 on Alpha ES47 7/1150
SAMBA 2.2.8
There are (or have been) multiple releases of Samba 2.2.8 on
http://www.pi-net.dyndns.org/anonymous/jyc/
Which one are you using.
I have had this issue ever since Samba was installed and have implemented a
fix of Stopping and Restarting the whole of Samba over a weekend to get
round the issue. I saw an article about the NMBD process crashing and the
only answer at that time was as I have already done.
at which time ?
The situation appears to be that NMBD process starts up as normal when the
server is booted or rebooted and runs quite happy for a period of time. The
NMBD process then appears to crash and I am unable to find any files or logs
that can help with diagnosing why. I then manually start up the whole of
Samba to get the NMBD process up and running.
I'm not aware of a crash, but I know that NMBD had problems with some system
resources, acquiring too many locks without releasing, or other resources.
You should at least have the newest release of Aug. 17, 2005:
http://www.pi-net.dyndns.org/anonymous/jyc/samba-2_2_8-src-20050817.zip
and related files.
However, I just looked on our system and saw that the lock problem does
still exist.
Please have a look at $ monitor lock, and see if you have increasing lock
counts. If you have, then you should kill the NMBD process, and watch the
lock display. This is what I found (only the "Total" parts shown):
NMBD (and about 10 SMBD processes) still running:

I didn't investigate further, but it seems that this could also be your
problem.
Any ideas, anybody? JYC ?
