I'm not sure about fusion-reactor, but the product SeeFusion does a pretty good job of staying de-coupled from Jrun and CF. Usually it will respond up until the JVM dies. Perhaps fusion reactor has a feature similar to seefusion's active monitor rules. you can have triggers shoot you an e-mail that show you all the running request and a stack dump at the time the server is slowing down.
A full thread dump of your JVM can be a little crazy. Just stick to the threads named jrrp-xx (I think) Those are the threads related to actual web requests. Most of the threads won't be doing anything. The ones you are about are the ones processing files. That is most helpful at a time like yours is to see specifically what requests are running and exactly what those specific requests are doing. That will help you narrow down all the stack trace stuff. IF you have something like an endless loop, you will see the threads stuck on the same like of code over and over as you pull a stack trace. The trick to reading a full thread dump is usually just looking for patterns. Anytime you repeatedly see a file/function coming up during your thread dump that is a sign you need to inspect what that code is doing. Please paste a dump from a single thread that you don't know how to read and we will point out the important pieces. ~Brad ----- Original Message ----- From: "Philip Kaplan" <[EMAIL PROTECTED]> To: "cf-talk" <cf-talk@houseoffusion.com> Sent: Wednesday, December 03, 2008 12:31 AM Subject: Re: Why is my CF8 server constantly hanging? >> When jrun is doing the 100% thing, look at the currently running requests >> > > in fusion-reactor > > Usually when Jrun is doing its 100% thing, FusionReactor won't load.
