I'm a web developer using j2ee. Frequently, I deploy a new version of my application in application server (Tomcat, JBoss, Oracle OC4j). During deploying, the AS don't reply http request for a specific path (of this application). In this condition, Firefox 3b4 uses 100% CPU. 

Reproducible: Always

Steps to Reproduce:
1. Deploy an application in an application-server.
2. Request specific application url in this application server during deploying.
3.
Actual Results:  
100% CPU usage

Expected Results:  
0% CPU usage

Error in Firefox 3b4. Ignore User-Agent Info!

You mean that you get high cpu if you enter a URL from a server that doesn't respond or does it happen if parts of a page are missing (images) ?
Is this http or https ?

Hi Matthias,

I mean I get high cpu if I enter a URL from a server that doesn't respond...


I guess I can explain better using wget:

server:  172.168.5.155
port: 7777
application: AutorizadorControlado
welcome page: index.faces (Java Server Faces)

wget http://172.168.5.155:7777/AutorizadorControlado/index.faces
--16:04:22--  http://172.168.5.155:7777/AutorizadorControlado/index.faces

If I'd used firefox "during long delay" moment I would have get high cpu.

Wayne. The answer is no. Since Firefox 3.0, the bug is not replicable anymore.
