I use many tomcat backends with nginx as frontend balancing proxy and have not seen this anywhere, if possible could you create a small VM linux distro with nginx to see what happens with open ports between nginx and the backends? All I can see in your logs is a timeout to the backend, this can be caused by anything, wrong expected http version, specific tcp parameters, etc..... Also try the older versions such as 1.4 and 1.2
