There has been "an abuse" (maybe not so far as an attack, I think an attack would take us completely offline) going on the past few days that is draining resources. A large set of IP addresses is walking through every web browsable link for every project. This includes cgit, viewvc, loggerhead, everything. This has been going on since the 14th. Perhaps someone is trying to mirror everything in an abusive way? I don't know. I have been watching it and trying to mitigate it. But there are a lot of IP addresses. The result is that it starves the system of resources. It consumes processes. It consumes memory. None of the failures you are seeing are hard failures. Another attempt and they might get through the queue ahead of the abusers. The ssh:// protocol and the git:// protocol uses a different set of processes and have their own process limits. ssh being the most permissive since that is a fully authenticated protocol. I think people using ssh:// are not noticing a significant problem. Since https shares with viewvc and cgit it is getting starved along with them. I have been traveling around myself since Thursday[1] which prevented me from having enough time to really dig into things. But I am back and looking at what might be done. However with distributed attacks such as this they can be quite difficult to avoid. I started looking in depth last night but unfortunately my first attemps to mitigate this didn't help significantly. I am digging into it in detail now. Bob [1] I left for Pogosa Springs on Thursday in my C140. But then had a fuel starvation problem with my left fuel tank! Vents are in the fuel caps. If they get clogged up then no air goes in. If no air goes in then no fuel comes out. No fuel comes out and the engine doesn't keep running. I landed at Boulder (just happened to be near me at that time) to sort things out. Thought I did. It is somewhat hard to tell when you are putting your mouth on the spout of the fuel cap and trying to pull air through to see if the vent is okay or not. (One of these days I want to build a fuel cap vent tester specifically for this purpose.) Took off to continue the flight. But then the problem with that tank persisted. I had to turn around and fly back home on the other tank. Redundancy is a good thing. Then much scrambling around with the mechanics trying to resolve the problem. But when you have a 1946 airplane the parts are not always immediately available. This one is going to need some digging. I really want to replace the fuel cap but getting an appropriate one isn't always available. This is where the vintage type clubs are great resources. It was late before I got back to my house. With the problem still not completely resolved. Needs more work. But I still needed to get to Pogasa Springs for a combined work trip and personal trip. Therefore on Friday I swapped over to a different airplane. I took my C182 down to Pogasa Springs instead. Sure the C182 is the better mountain airplane by a lot but the C140 is also just a joy to operate. In any case it was uneventful flying down and back. Flew back Saturday. Started looking at the Savannah resource starvation problems on Saturday night but was ineffective.
