High CPU usage on Knots node causing connections to drop

I’ve set the node up with continues profiling (using GitHub - mstange/samply: Command-line sampling profiler for macOS, Linux, and Windows · GitHub) and enabled debug=leveldb on all nodes. If it happens again, we’ll have more data to dig into it. As of now, I don’t think we can find out much more about the root cause from the data that we have.
