Brian, please forgive me if I am insulting your intelligence.
But are you sure that you are not just noticing the disk
buffering behaviour of Linux?
The Linux kernel will use up spare memory as disk buffers -
leading an (apparently) lack of free memory.
This is not really the case - as the memory will be released
again when needed.
(Ahem. Was caught out by this too the first time I saw it...)
Anyway, if this isn't the problem, maybe you could send
us some of the stats from your system?
Maybe use nfsstat?
