Hi Torsten,
could you extract a simple test application to reproduce the issue?
Please provide more information how you trigger the error. Which RAP
version are you using?
Thanks,
Ivan

It seems that this topic is not interesting for experts of Eclipse Community Forums. It's a pity...

Hi,
without a way to reproduce it it's hard to help and give any suggestion.
Please open a bugzilla and provide a snippet or some steps to reproduce
the issue.
Regards,
Ivan

That last stacktrace looks like it's caused by the Jetty idle timeout setting http://stackoverflow.com/questions/25548341/jetty-idletimeout
As to why it's taking more than 30 seconds for the browser to send the request, is there a server-push session active?

We have the exact same issue with rap 3.0.1,
We have a server-push session active.
It also happens more often with a laggy network.
