The best option is to set this to a sufficient value that covers your
situation. It doesn't currently allow infinite to stop situations where an
upstream ITSP would be continually hit with traffic. Giving it some thought
I think there's at least one area where it may possibly be improved, which
is for timeouts/no responses. In that case you probably haven't hit a
remote server so continued attempts would seem fine.

I'd need more information on this particular case to know whether that
would have resolved it though.
