We run our Zope installations under monitoring by NetSaint. My GSM phone
rings when Zope hangs, quite irritating.

Anyway, NetSaint checks a couple of times per minute, and we nevertheless
had Zope hangs. Yesterday there was an explicable one: we do whois
lookups, and the Belgian registration authority somehow dropped our
SYNC packets from the whois connection attempts. By the time <number of
threads> people tried to do a whois, Zope became of course unresponsive
(and my phone rang).

Just adding useless datapoints.... ;-)
