This generally means that the client aborted the connection before the server completed its response. Most of the time that means a user clicking Stop as a page loads, but I have seen it other times due to resource loading issues. For example, Dojo, at least through 0.3.1, was notorious for causing these because of its dependency loading mechanism, and I never did figure out why. I've seen it at other times with other libraries, and my own client-side code, as well.
In any case, they are generally not something you need to be overly concerned with. Certainly it's true that they consume resources, if for no other reason than the JVM needing to deal with the exception, but it's rare that you can do anything to stop these, and if anyone knows differently I for one would be extremely interested to hear about it :) I've never heard of it being a performance issue or anything like that (except I guess filling up a log file if its happening *that* much).
