I have a 5.1 server w/sp6 on it running currently only netware and ndps
that slows to a crawl after about 1/2 day. It is a pIII 1Ghz w/ 1gb ram,
on a mixed netware 5.1 and 6 network. I have completely rebuilt the
machine, and it works fine, for about 1/2 day, then crawls again. A reboot
will cure it for a while... Any suggestions?

Perhaps a memory leak? What controllers and NICs are in the mix?

Memory leak is prime candidate. Look at your % cache buffers after a reboot
and then as it slows down if they decrease you are leaking. If you're
leaking go to memory stats and record the top ten after a reboot and then
watch to see who keeps growing.

If you dont have "SET CLIENT FILE CACHING ENABLED=OFF" I've seen the issues
created by filesys.nlm slowly kill a server until a reboot.

It has an onboard Intel CE100b NIC, and onboard adaptec 160 SCSI
Controller.

I just changed the NIC today, and disabled the onboard one, as well I
disabled client file caching... Hope this works.

I suspect you will still have the problem -- SP6 installs driver updates
for the Adaptec controller as well -- and these drivers have memory leak
issues among other things.

Two choices:

1) Deploy SP7 -- which has now been released and includes the correct
drivers for the Adaptecs in its standard update driver set.

2) Staying with SP6, replace your adaptec drivers with those you will
find in the SP6 \tools\unsupdrv directory.

I am downloading sp7 now.

The DS.nlm file seems to be creeping upward in allocated memory as the
server runs...

OK -- let us know.

Hmm, I don't recall there were any DS specific issues in SP6. I know there
was the issue with the Adaptec driver (same driver problem in SP3 of NW6).

DS will do that, creep up some.

Tipping you over in 1/2 a day indicates something is not creeping, it's
gobbling memory at a pretty good clip. Or, it,s not a leak at all.
