          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Clustering
    Affects Versions: JBossAS-4.2.2.GA
         Environment: Windows XP

Hello, 
I have clustered two instances of JBOSS and I have configured the jboss web deployer for load balancing using apache http server. 
Consider I have 2 instances of Tomcat (embedded in JBOSS) say TOM1 and TOM2. 
Loadbalancer1 is TOM1 and TOM2 is Loadbalancer2 are configured in Apache server. 
A request is processed by TOm1 and it goes down(using Ctrl+C) the request is then load balanced to TOM2.In the mean I start TOM1 again. 
And bring TOM2 down...The request state is transfered to TOM1 and TOm1 restarts the processing of same request. 
The problem is that TOM1 throws an exception
