Unexpected EOF read on socket.
Mike Calvo
Hello,
I have been having an issue viewing the hystrix metrix stream and was wondering if anyone has had a similar issue.
I have an application built with Spring MVC and I am using Tomcat 7 for my application server. My application code works just as expected, but when I to navigate to loalhost:8080/web-app/hystrix.stream I am forwarded to the Tomcat Error - 404 page. In the tomcat log, the followign exception is thrown:

Has anyone encountered something like this before? As I mentioned, my the application itself works fine. It also appears that the hystrix sevlet is being returned accordingly, but it doesn't appear to be what's throwing the exception. I've used the Chrome Postman plugin to add the Accept and Content-Type = application/json headers to the request - both without success.
Thanks a lot.
