I was mucking around with the source code on a large research cluster that I have access to. For some reason the nodes were connecting and disconnecting from Freenode quite rapidly witch resulted in most of my nodes getting k-lined. Freenode started going nuts and blocking my nodes as fast as I was creating connections.
Not too sure if other people were k-line’d as well because of this?? However, the timing was “bang on”.
I had discovered the bug around the same time this k-line problem was reported. I ended up forcing the source to seed IPs from some Bitcoin clients that I run on a different network.
