I have a NW6.0 server; SYS is NSS, VOL1 volume is traditional...there are a
number of databases and files being accessed on the traditional volume.
Hardware is an HP DL380 P4 2.8 w/RAID card.

I upgraded from 2.5M to 4M RAM, and since then performance has suffered.
Long Term cache hits went from 83% to 71%. LRU sitting time went from 5-6
days to 2 days. A few users seem to have lost drive mappings, and had
trouble accessing Access and other databases/files on the volume.

No errors on console; the only thing strange I am seeing is a "work to do
response time" is suspect note in the server health logs.

Any suggestions? I thought more memory was always better, up to the point
of dimishing returns.
