When my node crashes, i get this error on reboot:
[Host Controller] 18:31:53,620 ERROR [org.jboss.as.host.controller] (Controller Boot Thread) JBAS010901: Could not connect to master. Aborting. Error was: org.jboss.as.host.controller.RemoteDomainConnectionService$HostAlreadyExistsException: JBAS010832: There is already a registered host named 'worker0'
According to the following thread, this should be "solved":
I guess that this behavior may be desired in some cases, but is there a flag or configuration to allow my hosts to come back automatically after killed?
this was fixed in latest nightly builds, so if you are not already please try with latest 7.2.alpha builds.
Let us know how it goes with newer version.
