> When you set up a remote as7/eap6 and start the server, a second deployment scanner is added to standalone.xml on the remote server. It is set for the same dir as the default one. Thus you end up with two deployment scanners pointing to the same dir which results in weird behavior of deployments.
> These are the two scanners that you can see in standalone.xml after the remote server is started:
> {code}
>             <deployment-scanner path="deployments" relative-to="jboss.server.base.dir" scan-interval="5000"/>
>             <deployment-scanner name="jbosstoolsscanner1" path="/home/rasp/jbossqa/runtimes/jboss-as-7.1.1.Final/standalone/deployments/" scan-interval="5000"/>
> {code}
> You can see the additional scanner was added right after server start:
> {code}

> {code}
> As you can see you have two scanners noticing this war and both try to deploy it. The result is non-deterministic. Sometimes you end up with the module deployed, sometimes undeployed.
> Note that this only happens if you set up the management port for the remote server. Because if you don't do that, no management connection is made to the server and so the additional deployment scanner won't be added.
