This is a customized application running on AIX, using this port and this is specified in /etc/services. When ever the application starts it looks into /etc/services uses the specified port to come into service, unfortunately due to some bug, the application hangs and few of its processes goes into exiting state:
# ps -eaf | grep -i exiting
root 10996 53590 1 10:46:01 pts/1 0:00 grep -i exiting
- 12472 - - - <exiting>
- 22580 - - - <exiting>
- 23476 - - - <exiting>
#
After this the port get stuck and when I restart the application, it fails to start saying that the port is in use. So I have to edit the /etc/services file and change the port to another one.
Since the application get hang then and there, now on the system there are lots of port which are stuck.
Also ports are not getting cleared up by itself, even after the timeout. It remains in LISTEN mode for ever, unless the system is rebooted.
I beleive if there is a way to clear up the exitung processes without rebooting the system, then it will clear up the system.
Is there anyway to kill the exiting processes ???

I'm trying to release a port 7601
I do a netstat -an which is returns
*.7601 *.* 0 0 49152 0 LISTEN
I assume 49152 is the process running the port. Is this correct? If so, how would I safely terminate the process?

services
SERVICES(5) BSD File Formats Manual SERVICES(5)
NAME
services -- service name data base
DESCRIPTION
The services file contains information regarding the known services available in the Internet. For each service a single line should be
present with the following information:
official service name
port number
protocol name
aliases
Items are separated by any number of blanks and/or tab characters. The port number and protocol name are considered a single item; a ``/''
is used to separate the port and protocol (e.g. ``512/tcp''). A ``#'' indicates the beginning of a comment; subsequent characters up to the
end of the line are not interpreted by the routines which search the file.
Service names may contain any printable character other than a field delimiter, newline, or comment character.
If ``db'' is specified as source in the nsswitch.conf(5), /var/db/services.db is searched. The database in /var/db/services.db needs to be
updated with services_mkdb(8) after changes to the services file have been applied.
NIS INTERACTION
Access to the NIS services.byname map can be enabled by adding a single ``+'' on a line by itself in the /etc/services file. This causes the
contents of the NIS services map to be inserted at the location where the ``+'' appears.
FILES
/etc/services The services file resides in /etc.
SEE ALSO
getservent(3), nsswitch.conf(5), services_mkdb(8)
HISTORY
The services file format appeared in 4.2BSD.
BUGS
A name server should be used instead of a static file.
