Those send que size messages can be ignored. They are stuck connections where the peer stopped responding. Unfortunately the code doesn't do a great job of ignoring those cleanly.
If it bothers you a lot just restart the node.
Yeah restart and ignore. Hehehe, I wonder how did you make it to such significant price increase. Code is so broken that it's almost useless. I was hoping for much more unders smooth's lead. However there's always a bunch of idiots that will fall for the hype. Good achievment!
