Hi all: First off, I do not understand the black art of
server memory tuning. I have been getting the following
errors from several servers lately:

Cache buffers fell below threshold of 40% on server XXXXX.

All servers are identical HP DL385's with 2GB memory. They
all run NW6.5 sp7.

I have looked at various TIDS but can't seem to solve this.
Can yo point me in the right direction?? Chris
