We are running wildfly in domain mode with the following configuration.

host A running domain controlller
host B running host controller with one app sever
host C running host controller with one app server
host D running host controller with one app server

When we deloy war using jboss-cli the web console is blocked for usage until deploy completes. I have run jvisualvm and it does not appear that domain controller process is starved for resources (cpu, memory, threads).
