OK. The next one would be the tcpdump during that
interval to see actually the status of the sockets
both on mod_jk and JBoss boxes.

It's obvious that

shutdown(socket, SHUT_WR)
poll(socket, 2 seconds)

caused poll call to time out, meaning that
the JBoss side didn't respond to the
shutdown(socket, SHUT_WR) call by
closing it's side of the connection.

BTW, do you have "lingering bytes in 0 sec" messages
in your log or lower then 2 sec?
