The strange thing is that GNU Emacs does something similar, though

a much less frequent basis. Assuming that VM and GNUS are from
disjoint code bases, but the Emacs' are not, doesn't it seem likely
that Emacs is somehow the source of this behaviour? I wonder if anyone
else has this problem.
The problem likely has nothing to do with any of the named
programs. DNS lookups fail sometimes. UDP packets are dropped,
DNS servers get overloaded, etc., etc. ISP caching servers are
notoriously overloaded.
