Memory issues on NW6.5 SP4

2GB of memory
GWIA,MTA box with GWAVA

I only know of the seg.nlm util used in conjunction with memcalc.exe tool
to calculate the proper -u amount. This server does not qualify for this
tool though because it has -2gb.

Any ideas on how I should calculate the -u amount or should I be looking
at another issue?
