It would start responding intermittently and then stop responding completely. This particular Tomcat has a second HTTP connector pool for an Apache httpd using mod_proxy_http. That pool kept working beautifully. I went back to 6.0.x and now it all works beautifully, as I am used from Tomcat. I tried reproducing it on a load test machine, but it never showed there. I am at a loss where to start looking for this.
