netstat -a | grep 500
hostname.500 192.168.0.1.36053 16560 0 66608 0 ESTABLISHED
hostname.500 192.168.0.1.36054 5840 0 66608 0 ESTABLISHED
hostname.500 192.168.0.1.36055 5840 0 66608 0 ESTABLISHED

hostname.500 192.168.0.1.36073 16560 0 66608 0 ESTABLISHED
the application connection its connect through port 500 to another application, but if we see the bold one is mean that the tcp connection not binded to the another application server.
how to release or refresh the tcp connection to not bind "bold" ?
please advices
thank you

fair(7) BSD Miscellaneous Information Manual fair(7)
NAME
fair -- simple TCP load balancing service
DESCRIPTION
fair is a load balancer for TCP connections. It can be used to distribute incoming connections for SMTP, HTTP or any other TCP service to
multiple hosts, distributing the load as evenly as possible.
fair consists of two daemons. The carrousel is the front-end; it keeps track of back-end hosts and their status, and forwards incoming con-
nections to the back-ends in such a way that the load is distributed fairly. The transponder runs on the back-end hosts, it registers with
the carrousel and sends it status information. The TCP connections forwarded by the carrousel are not sent to the transponder daemons but
are sent directly to the desired service running on the back-end host. Both daemons share a single configuration file.
EXAMPLES
The following example shows how to set up fair to service HTTP connections and to distribute them over back-ends in the 192.168.1.0/24 sub-
net.
The configuration file /etc/fair.conf contains the following:
WorkerService = http
BalancerService = http
AllowUDP = ^192.168.1.[0-9]+$
On www.example.com, the front-end server receiving the incoming HTTP connections, just run:
carrousel
On each of the back-ends run:
transponder www.example.com
