close tcp port

Hello, I have a service running (ODBC) and every now and then it will hang and I will have to stop and restart the service. The problem is when I stop the service, it indeed stops the service, but netstat reports a tcp port still open with the fin_wait_2 status. Then I must close the client application to allow the service to restart or wait 5 minutes. How do I make it close automatically and not wait for 5 minutes? I thought maybe if I defined the service in /etc/inted.conf as nowait it might help but either that is not how it's done or that just doesn't work that way.

I added this: (copied from another service in the file and adapted it)

tfodbc stream tcp nowait root /usr/local/tsobdc/tfodbc.sh start

It did not break the service, it still works fine. There is also /etc/services. can I add anything to that to define this program as a service and have it so that when it stops running it closes its ports? This is AIX 4.3

Thanks

update-service(8)					      System Manager's Manual						 update-service(8)

NAME
update-service - add/remove a service to/from system-wide service supervision SYNOPSIS
update-service --add|--remove service-directory [service-name] update-service --list|--check [service-name] DESCRIPTION
service-directory must be a directory to be used by supervise(8), service-name must not start with a dot, and must not contain a slash. update-service adds or removes the service-directory to the system-wide service supervision provided through daemontools' svscan(8), lists all registered system-wide services, or checks for a specific service-name whether it is registered. When adding a service, and the service-directory resides in /etc/, update-service makes sure that the ./supervise/ subdirectories in the service-directory, and the optional service-directory/log/, are symbolic links pointing into /var/lib/supervise/, unless they already are symbolic links. OPTIONS
--add | -a Add the service directory service-directory to the system-wide service supervision, under the name service-name. If service-name is not specified, update-service will use the basename of service-directory. You can use the svc(8) program to control the newly added service, and the svstat(8) program to query its status, e.g.: # svstat /etc/service/service-name --remove | -r Remove the service directory service-directory, which has been added under the name service-name, from the system-wide service supervision. If service-name is not specified, update-service will use the basename of service-directory. When removing the ser- vice-directory, the exit command is sent to the corresponding supervise(8) process, telling it to take the service down and exit afterwards. You can use the svc(8) and svstat(8) programs to control the removed service, or query its status, e.g.: # svstat service-directory --list | -l If service-name is specified, update-service checks whether service-name is registered as system-wide service, prints a message and exits non-zero if not, or prints the service-name and the directory it points to and exits zero if yes. If service-name is not specified, it prints the names of all system-widely registered services, one per line. --check | -c The same as --list, but update-service doesn't print anything to standard out or standard error. ENVIRONMENT
SVDIR The environment variable $SVDIR overrides the default services directory /etc/service/. FILES
