I see HN refuse connections many times every day without any clear reason on my end, I've asked two other people to test, one had the same problem for the other it worked fine so it is a bit flakey.<p>It's usually accompanied by HN slowing down and returning a page in 6-10 seconds or so.<p>My guess is (but I really am poking in the dark here) that it has something to do with the accept queue overflowing and the network stack sending out RST packets (I've seen those using tcpdump so they figure in there somewhere).<p>Alternatively the 'listen' gets dropped.
Ask PG: Can you please fix the connection resets and / or explain them?
