A WMB 6.1 HTTP request node is configured to connect to a WAS 6.1 on an XP workstation to port 9080.

To allow socket reuse:
HTTP protocol is set to 1.1
Request timeout 120
HTTP 1.1 keep alive is enabled

To elminate the web server as a potential source of the issue:
Web browsing to the URL creates an established socket followed by a clean close when the user closes the browser window.

Symptoms
The broker flow makes multiple request to the same URL and subsequently receives a reply w/o errors. However, the host reports multiple sockets in FIN_WAIT while queried via

netstat -an | find "9080"

It appears that the HTTP request node is making a new socket connection for each request and is also not closing the previous socket before requesting a new one (?)

I am interested in learning if there is a fix to reduce the max number of connections to just one and eliminate the FIN_WAIT

The same setup going to an AIX WAS maintains a single socket in established mode. We are good to go, as the XP workstation was just a standin before a longterm setup was achieved.
