[Zope] Exception within ZServer hangs Zope

Hello, Zope users!

Has anyone seen this? I causes zope to just hang, and I don't have
a clue as to where to start looking. It seems it happens within the
ZServer, but I couldn't find a line in the entire tree of Zope that
would assign a suspicious value to that 'p' variable. Can anyone
suggest how to detect this and at least restart Zope, as this is
causing us service outages (the question is really how to properly
programatically restart Zope, as if you push Restart Zope within
the control panel). Is killing -15 zope processes safe?
