Have been searching thru the discussion threads and see a lot of threads
on nw6.5 memory issues. I was getting "low available logical memory" on
my servers. (they had 2.5GB RAM).. I just added more RAM to them, and
they now have 4GB.. However Im still getting the low available logical
RAM.. I do not have any -u paramaters on the server.exe file.
I have attached a segstats.txt file if someone could take a look
please.. I did see that NSS and DS is taking a lot of memory..
Our NW6.5 servers all exhibit the same symptoms, so I assume whatever
gets fixed on this server, may be necessary on the others as well.
PS: I added the ram to this server yesterday, no real load on the server
right now since we are a k12 school district and the kids are out for
the holidays, but the server still went to the "low available logical
ram" in NORM within 1 day

Thanks in advance and have a great holiday
