Forgive if this question has been asked somewhere else.
I have 2 NW65 SP5 (fully patched) file servers with 5 GB memory, 7 300GB
drives ( 2 300 GB mirrored sys, 3 300GB data, 1 300GB HS).
Logical space and available memory on these servers appear to be dropping
gradually, causing the servers to be restarted consistently after few
weeks of uptime. Running the memcalc utility and apply the recommended
values has proved to be hopeless.
After reading several postings in the forum, I've realized that several
are experiencing the same problems. Is it safe to assume that the only
way to solve this malignant is to reduce the memory to 3 GB ?

Here isa the segstats:
