Increasing xmit_timeout reduces the number of attempts to resend LEAVE_RSP when the destination is no longer reachable. TCP already retransmits messages, so the UNICAST3 retransmission is only needed when the connection is unstable or the destination's thread pool is full.
Reducing conn_close_timeout reduces the number of attempts to resend LEAVE_RSP when the destination is no longer reachable.
