Ronald, thread dumps contain the native ID of threads, and ps can output such IDs as well, so you can match the output together. Been there, done that. On Thu, Oct 16, 2008 at 7:16 PM, Ronald Klop <[EMAIL PROTECTED]>wrote: > Filip, > > How do your top or ps commands relate to threads in the thre

Hi, Lindsay, Sorry for my ignorance, but seeing that you were trying to locate the thread using "PID", I think perhaps it's wrong. I have the same experience identifying such a CPU utilization issue on a Debian box using a 2.6.x version kernel. I cannot recall whether on a 2.4.x kernal linux box y

Re: Auto Reload Features by Tomcat

2006-06-02 Thread Jerome Jar
I think it's because that you just enabled the "Auto Build" feature of eclipse, so every time you changed your java source, eclipse built it for you, and tomcat saw the class files changed and then reloaded that context. But when you metioned "for my production", I guess that machine do not have a

I think eclipse was just unable to validate that xml file, it's likely the DTD file cannot be fetched by eclipse for some reason, e.g., network problems, DNS resolving failed. It's not a tomcat related issue. 2006/5/24, [EMAIL PROTECTED] <[EMAIL PROTECTED]>: I created a dynamic web project in Ec

Well, I think -Xnoclassgc is horrible. And singleton objects cannot be shared among different application contexts, because they use different classloaders. Shared objects is better held in somewhere else, e.g., JNDI, although I usually blame it =) 2006/5/22, Corobitsyn Roman <[EMAIL PROTECTED]>:
