What about for your test server?
What are the loads/restart frequency of the test server?

So I make sure I understand:
o Your Data.fs is ~525MB
o Zope's memory usage starts at 1t ~18MB
o Zope's memory usage grows for there
o Uptime: Zope is restarted (or is the machine restarted?) a few times a
week

Right?

What os is it running?

Just trying to narrow by process of elimination....
When you put Zope on the big boy, was it a clean install, or was it
copied over from the test machine? If the latter, I am presuming it was
rebuilt, correct? What about options to the compiler (if any), such as
optimizations, architecture-dependent flags, etc.?
