      iii)use as7 cli subsystem to (stop*/enable*/disable* -context) for the deployed to node1 webapp successfully.
      iv)Submit one command to enable/disable for node1 using http://host:port/mod_cluster_manager
      v)Now attempt to execute similar commands with cli subsystem.

    Description

      With a modcluster setup if you are using the cli subsystem (stop*/enable*/disable* -context) operations to modify contexts successfully and then you or anyone else uses the http://<ip address>:<port>/mod_cluster_manager to enable/disable any contexts then continued operations by cli stop working. The only fix in this situation is to restart the http instance which is pretty bad.

      It appears that the two mechanism to communicate with the http modcluster manager clobber each other in some way with the cli subsystem loosing the ability to make changes.

      Additionally we should add something to the release notes suggesting to disable/deprecate the usage of mod_cluster_manager. However this should be resolved more completely because as7 subsystem commands from a completely valid setup simply won't work with no feedback.

      Note: mod_cluster_manager commands and operations continue happily.
