I do not know why this problem happens.
But, I probably know a work around.

The error occurs because Zope tries to resolve an IP address via DNS
(Domain Name Service). There is a configuration option to disable
this name lookup.

It is highly recommendable to disable it, as DNS lookups can be
very expensive (you have an additional reason).
