I have been using vmstat (utility hidden in /systest/ssr_util) to
try to measure the stress on the virtual memory system on our
Apollo network. I understand the VAX virtual memory system very
well and have used monitor to illustrate the memory needs of
various task/OS combinations but I don't know if the same 
info can be extended to the Apollo's. For example if I had a free
list size of 0 on the VAX I would know I was in trouble.

Can anyone shed any light on the figures return by vmstat and has
anyone out there got a source of info on the Apollo VM system in
general?
