You really aren't giving enough detail in your messages. You are trying to treat a complex problem (hundreds of transactions per second) as a simple, something is wrong with one thing issue. Scaling performance to these levels is usually a combination of factors. There are rarely magic bullets when it comes to things like this.
What JDK are you using? Have you tried using different JDKs? What operating system are you using? You said WinNT in your initial post. Is that WinNT 4? What service packs have been applied? You never posted a response as to whether setting enableLookups="false" made any difference. What test tool are you using? Are you sure the issue is in Tomcat, and not in the test tool/station? I assume you have IIS installed. Have you tried using the same test tool to put 200 connections per second to IIS? Have you tried scaling your transactions per second upwards and observing the behavior at different loads? George Sexton MH Software, Inc.

When I run tests at a high TPS, I might encounter a "can't connect" error (looks like I've reached the acceptCount limit). That's fine with me, so I stop the test and get ready to start another. When I start the next test (I usually wait a few seconds, let tomcat's CPU usage drop off), I immediately start getting "can't connect" errors, which should not be possible in the amount of time I'm getting them (TPS of 100, acceptCount 1000, that should be 10 seconds before I should get these errors, right?) My only "fix" for this problem is to shutdown and restart Tomcat, which is not really a solution. Is this a known problem or bug? Possible I misconfigured something?
