Small - 50 MB.  My above comment was more of an 
inane introduction, sorry. I didn't really think
this could be the cause.

No, we could not connect to the Zserver directly.

Sorry, you're right, it was 'spinning' - 100% CPU resources.
Does that suggest anything in particular ?

When this first occured, I restarted Zope. That solved the problem
for a few hours but problems kept recurring. Last night I restarted 
the server and since then it has been OK (for the past 8 hrs) ... 
but I'm anxious how it will stand up to being put under load again
today.
