I hadn't actually restarted the server in weeks.

Thanks Teodor... I've found that the only way to solve this was also
to restart my server - FreeBSD 3.2  - but this calls to mind the previous
discussions we had on the list concerning Cold Fusion (and staff whose
job it was to restart the servers when they hung).

I would try upgrading to the latest version of Zope (ie. replace 2.01
with 2.1) and even replace PCGI with FastCGI but the www.zope.org site 
is absolutely crawling at the moment (didn't DC upgrade the server 
and split the mailserver off onto another machine last month ?) so 
I can't even download the src (in fact, I'm getting a lot of "document 
contains no data" errors).

Thanks for your help - I'll check ZMonitor too ....
