      With default and non distributable context or draining strategy set to ALWAYS.
      stop() or stop-context is called with waittime set to 0
      Session drain

      2017-05-10 09:18:21,953 INFO  [org.jboss.modcluster] (management-handler-thread - 2) MODCLUSTER000046: Starting to drain 1 active sessions from default-host:/clusterbench in 0 seconds.
      

      Issue
      This should immediately fail to drain session and send stop node/context to balancer.
      However, it looks like it is waiting for session to timeout

      Context/Node is disabled on balancer

      "context" => {"/clusterbench" => {
                              "requests" => 0,
                              "status" => "disabled"
                          }}
