None. I've seem the same problem but haven't got to the bottom of it
yet. What I do know is:
- Tomcat doesn't send a close
- The browser closes the connection on its own
- Tomcat tries (and fails) to write some data and that triggers the
  close on the Tomcat side

I'm wondering if some form of data corruption could be the trigger.

Whatever is going on, I'm fairly sure it is a different issue to BZ 55633.

I need to do some more careful analysis with Wireshark.
