That quite clearly looks wrong, I agree. The problem here is of course to
figure out how it got to be that wrong in the first place. The source of the
problem rather than the sympthom I mean.

A specific fd is just a descriptor for a socket, and that socket may be
representing a TCP connection and that TCP connection may of course still be
"up" and there are a few basic checks one can do but none are guaranteed
success. And I don't see how that would help in this particular case anyway.
