I have not looked at the main site at all, only the forums, as I mentioned in my original post . It looks like the error you posted is actually a Tor error message. I see reference in Tor support tickets to several variants of it: https://trac.torproject.org/projects/tor/ticket/1519 Jun 08 20:41:28.171 [Info] connection_ap_process_end_not_open(): Edge got end (connection refused) before we're connected. Marking for close. for example. I don't see any reference to it with (server out of resources) , but it is pretty apparent what that error message means. So it seems like there is a resource exhaustion attack against the server, from that error message. Please post the link to the main site for me, I literally never go there so I don't even know the .onion for it. Are you able to establish circuits to it? In your previous post you said that you can send introduction cells but never get a response, that would indicate the introduction nodes are being DoSed. If you get an open circuit but streams close, that means that the problem is not with the introduction nodes. Digging up that error message in the Tor source code to see exactly what triggers it.
