We have implemented Servlet 3.0 AsyncContext in Tomcat Version: 7.0.23.
It runs on RHEL 6.1 using OpenJDK version 1.6.0_24,64-bit server
The app works great for the most part. If any network violations occur, updating from the server cannot reach the client, because there is an exception " ClientAbortException: java.net.SocketException: Broken pipe ". which is caught and ignored.
It happens on a line,
asyncContext.getResponse().getWriter().println(updateStr);
After that, Tomcat goes crazy and redirects URLs to unexpected servlets. For example, when matching / query with the SessionManager servlet, the URL mysite.com/index.html directed to the SessionManager servlet. Restarting tomcat solves the problem.
Any guidance on why this is happening and how to solve it?
