TCP internals showed an established Web Server port 80 connection to IP address:
24.155.219.60
Yet there was no such connection showing in the web server log.
I shut the web server down and restarted it and the connection went away.
Has anyone else run into this?

Are you sure there was no such connection in the log file?
Maybe for some reason it was not disconnected correctly?

I lost the listing in the window when I restarted the server and did not have configuration set to trace.
However, I do remember the connection was established at 2 pm when I noticed it and the last entry in the web server window was at about 10 am. Hindsight being 20-20, I wish I'd taken better notes. I'll check my router log, come to think of it. Did that. It does not keep info for more than 5 minutes or so.

Stranger Still:
I did however make a note of a second 80 connection briefly before the one reported above to IP address 64.246.165.237. Its kind of like it changed IP address while I was looking arround for a cause then new one went away entirely after the cold restart. It did not go away just hitting the sart and stop buttons of the server. I'll keep my eye out from now on.

I have not heard about this behavior before.
But I think you should enable the log so you can trace the communication for situations like this.

An established connection situation has reoccured. However, THERE IS a log entry. It follows:

01/18/2008 09:03:58.686 [1768] Client connected from 190.74.203.73
01/18/2008 09:03:58.696 [1768] Client disconnected from 190.74.203.73
01/18/2008 09:03:58.916 [3456] Client connected from 190.74.203.73
01/18/2008 10:04:48.303 [592] Client connected from 161.231.132.14
01/18/2008 10:04:48.303 [592] Processing HTTP request for domain: 'www.antrimgraphics.com'...
01/18/2008 10:04:48.303 [592] Sending file: C:\WebSites\AntrimGraphics\The Last Page\Alfred Florio\Last Page - Alfred.html
01/18/2008 10:04:48.303 [592] Response: 200 OK
01/18/2008 10:04:48.323 [592] Transfer complete
01/18/2008 10:04:48.333 [592] Client disconnected from 161.231.132.14

TCP internals showed a sysproc timewait for ip 161.231.132.14 at 12:50 pm. Nearly three hours after the connection.

At this point, I stopped the web server and the timewait went away, but then an established connection to the web server appeared in the tcp internals window which was not there before to ip 190.74.203.73.

Hope this helps.

The log of QnE Web Server looks ok to me, are you sure there's something 'wrong'?

One thing that catches my attention is that three hours later there is no disconnect for 190.74.203.73. I can only guess that the web server may need to time this out since there is no activity or is there?

The GUI version of QnE Web Server does not 'kill' idle connections.

However the service does have this feature.
You can specify the timeout for idle connections of the service version here:
HKEY_LOCAL_MACHINE\SOFTWARE\Pablo Software Solutions\Web Service\Settings\Timeout (= DWORD)

The default value is 900 seconds
