Hi,

I'm new here and need some help. As part of an Identity Management
solution we have installed to NDS/IDM server into our tree and have placed
all the replicas containing user objects in out tree on these two
servers. They are NetWare 6.5 sp4a running eDir 8.7.3.7 on HP proliant
DL360G3s with 4 gig of RAM. We haven't deployed out IDM solution yet, and
before we do the servers need to be stabilized. Currently we have to
restart these servers every night to ensure they have enough cache buffers
to run properly. Below is a message that currently appears on the console
screen on both servers, this only difference being the number on the -u
switch. If left the servers will start to display short-term memory
allocator errors and eventually stop synchronizing and communicating
altogether. I have downloaded and run both the config and seg nlms and
posted below. If anyone can give some advice on how to tweak the memory
usage on these servers so they can stay up for an extended period of time,
I'd be grateful. I have not posted the end of the config.txt file as it
lists the _netware dir files... It is about an additional 3000 pages!

Thanks,

Kirk Bellamy

Server logical address space is running low. Increase the available
logical space by restarting the server with the -u671252480 switch
