Re: strange periodic socket exceptions

Is this when you are using SSL with a Microsoft Internet Explorer?
And is it when there are multiple resources being sent down the same SSL
connection?

If so, this could be a known Microsoft bug.  Make sure your clients have all the
latest Microsoft security patches.  If this is not feasible, you can turn off
the HTTP 1.1 persistance in the server, which will work-around the Microsoft
bug.  Check the archives for the words Microsoft, IE and SSL.

Or it could be something else entirely!  Hard to tell when you've got non-Jetty
code in the stack trace.

It could be that there are two attempts to destroy the same connection.

What exactly do you mean by "slow down the application"?  As observed where? By
how much?
