I have seen this, too. But up to now only on Solaris.
You appear to run on Linux?

In my case, the problem disappeared almost completely, when I periodically
checked Zope for availability. I made the funny sentence: Zope does not
like to be lazy...

It might also be a resource problem: some scares resource (e.g. a
file descriptor) is not freed. If you are lucky, you may see
some entry in Zope's log file (search mailing list archives
for "STUPID_LOG_FILE") or it standard output/error (redirect them
to files).
