> Update on extended stress testing: After four days of testing with > 7200 clients everything is still looking good with 29 million > connect/disconnect cycles
There is one bug you should be aware of, although I assume you've yet to see it in your testing, perhaps it only effects the non-threaded web server component or is related to some thing else in my web application. Basically, about once a month on my public SSL web server with about 100,000 requests a month and 50,000 SQL lookups, I see: !!! Application Exception Big - Unable to create TIcsWndControl hidden window. Error #8. I have various memory and handle diagnostics in the application but they have never shown anything obvious. So my solution is simply to email a warning and stop the Windows service, it's set to restart if it stops, so the server is up again in about 10 seconds and the problem goes away for a few weeks. Not ideal, but workable. The problem persisted after I upgraded from a Windows 2008 server to a faster 2012 server at Xmas, but never happens on my lower usage back up servers. You can see the main server status page at: http://www.telecom-tariffs.co.uk/serverinfo.htm The server uses my Mail Queue Component to send status emails when it starts, stops and has errors, they are queued and retried so never lost if they can not sent immediately: http://www.magsys.co.uk/delphi/magics.asp These are two of the little things that really help with long term support. I've previously done contract work with ICS client server applications, similar in concept to yours, but only 500 clients (British buses) and up time for the servers was sometimes several months (my customers rarely did Windows Updates since this was a private WAN).
