samba - May 2001 - Shared Memory Problem

I'm running 2.0.5a on an HP 9000 N-class, HP-UX 11.00.  It was compiled with

MAX_OPEN_FILES set to 10000, but the shared memory size was left at the default
of

(1024 * 1024).  After a time, we are running out of shared memory and we have to
restart

the Samba daemons.  Looking at the documentation for smb.conf, clearly you can
change the

shared memory size, though it cautions you that you should be very familiar with
the

source code before changing it.  Well, I'm not.

I'm looking for recommendations for a server with approximately 100 Samba
users, who tend

to open LOTS of files.  System as above with 1.5GB of RAM.  What should
SHMEM_SIZE be?

Should I modify it simply by adding a global entry to smb.conf or do I need to
recompile?

Any assistance would be appreciated.  Thanks.
