I installed sp4a last month. Since then the OS cant see 3/4th's of my
memory. I have 2Gig installed and it only sees around 500mg. Running
"memory" command from console shows all 2Gig of memory - but looking at
health stats in Remote Manager only shows approx. 500mg being used on max
and avg.

Before this I could see close the 2Gig as max and 1/2 of it in use. A
reboot did nothing for this. The console monitor screen shows my original
cache buffers at 523,126 and my total cache buffers at 244,088.

The only thing running on this server is eGuide and GroupWise which I just
upgraded to 7 a week ago. This upgrade didn't change the issue either. It
is running but feels slow on the client side.
