I have seen this in cases you described (pushing stop, or closing the
browser) after the servlet has started sending output. Obviously, users
never see it (they pressed stop or closed the browser), but it does show
up in my error log. I finally added code to catch and suppress it in my
servlet.

I wondering if no one has come across this problem or is it just to
broad of an exception?

Subject: Socket Exceptions
I'm trying to get an idea of the root cause for this exception, does
anyone
have an idea? Could it have anything to do with dropping connections,
users
pushing stop or the number maxProcessors? I haven't really got an idea.
I
am not using Apache at the moment, just straight Tomcat with the Coyote
connector.
Thanks,
John O'Neill
