[jboss-user] [Clustering/JBoss] - can deployment on 2nd instance cause a undeploy on the first

[rajeshchande]

Hello,

JBoss: 4.0.3SP1
OS: Solaris 10
JDK: 5

I have two Jboss instances setup in a cluster fine in all respectes running fine. The farm deployment is working fine. But off late I observe one issue. The details of the issue are as follows. Whenever I deploy a WAR file on the first instance, it gets successfully deployed

Output from first instance after deployment of WAR file :

As soon as after the above output in the second instance, the first instance undeploys the WAR file deployed few minutes earlier with following output.

######################

Can anybody help me understand better, whats going on here? and how to avoid this undeployment?

Is the second instance triggering this undeployment? How to stop that?
