Request Help: Tomcat and Quad core processor

Hello,

I need your help and advice in resolving the following SocketException error
I am getting from the catalina.log file.

Apr 14, 2008 8:05:54 AM org.apache.jk.core.MsgContext action
WARNING: Error sending end packet
java.net.SocketException: Software caused connection abort: socket write
error

org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684)

The specifications of the server is:
Dell 2950, 4GB 667 MHz (4x1GB) RAM, Dual Quad Core Xeon Processor,
Windows 2003, IIS 6.0, JDK 1.5.07, Tomcat 5.5.17, ISAPI Redirector 1.2.14

I have another test server on the same subnet with the same specifications
mentioned above except that it has Dual Single Core processor. This server
has no problem.

Please let me know how this issue can be resolved.

Thank you very much for your time.

Regards,
Subram

That one should probably be moved down to DEBUG.  It is caused by mod_jk 
being over-aggressive in recycling connections and/or the browser closing 
the connection once all of the content has been sent.  I'll take this one.

Hello Mark,

I confirmed that the users do not click on any of the buttons (stop,
refresh, back etc) before the page gets loaded on the browser. The users
have occasionally received the following message on the browser.
"Software caused connection abort: recv failed"

Thank you.
Suhas

Tell your users not to click on the stop button whilst waiting for their 
page to appear.
