I have a web application that send a Push when a user to something that interest at an other user.

Sometime the push don't arrive at the other user.
This use case happen when i have this log at the server:

It is possible that i need do the shutdown every time that the Response has done and the servlet has finished?

That seems very unlikely, but I'd need to know a lot more about how your application is set up to say anything useful. When are you creating a push manager? When are you shutting it down? What happens within the lifecycle of a servlet request?

…so in the absence of more information, I think the most likely case is that your connections are closing and your networking layer just isn't noticing it until you try to write something. Setting an idle connection timeout (see #116) should solve this problem. Please post a comment here if you think that's off the mark.
