What jdk? - Original Message - From: Jerry Jalenak [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, April 19, 2004 5:19 PM Subject: Configuration Issue? HELP! Hi All, At my wits end on this, so thought I'd ask the guru's. 8-) We are running an Apache HTTP 2.0.49 / mod_JK 2.2 / Tomcat 5.0.18 environment on a Dell 1750 server (2 - 3.06Ghz CPU's / 4GB memory). We're running RedHat Linux 9 as our OS. We also have the hyper-threading option of the server enabled, so our two CPU's look like four. Here's the problem: After about an hour, my web application simply stops responding. There appear to be no errors logged in any of Tomcat's logs (except for some indications of a 'Broken Pipe' someplace in the JK connector. I think this is due to a browser being closed before the response is complete.) I also don't feel that this is an application issue; the app was developed on a Win2K box running Tomcat 5.0.18, and tested on a (different) Linux server running Tomcat 5.0.18. Neither of these environments have exhibited the 'hang' that I'm seeing on my new server. I suspect that it might have something to do with the hyper-threading, but can't seem to find any hits on the 'net about it (been googling all afternoon on this.) Does anyone have any experience with this type of environment? I really at a loss to explain what is going on here. 8-( Thanks.

Try googling for LD_ASSUME_KERNEL to see if that helps you.

Re: Configuration Issue? HELP!
There have been some post on JDK and hyperthreading. I think that it was stated that the new 1.5 JDK is much more friendly to hyperthreading.
