You could mark them as bogus. See the "server" statement.

However, if you're exhausting hundreds of file descriptors on these servers,
chances are that you *need* to talk to them. If so, then you may have to deal
with the underlying problem -- why you can't talk to them or they can't (or
won't) answer you.
