      Description

      On a multi-interface Windows box

      Even though the EAP balancer instance is bound to an IP address, 10.40.128.61 in this case:

          <interfaces>
      		 
              <interface name="management">
      		 
                  <inet-address value="10.40.128.61"/>
      		 
              </interface>
      		 
              <interface name="public">
      		 
                  <inet-address value="10.40.128.61"/>
      		 
              </interface>
      		 
          </interfaces>

      , it advertises a hostname as its Manager-Address. The receiving worker node then might have troubles calling the balancer if it translates the hostname to a different IP address (interface on the same box...):
      Balancer:

      Worker:

      MODCLUSTER000043: Failed to send INFO command to atomic-0.yada.bla.bla.redhat.com/169.254.47.37:8847: Connection refused: connect

      i.e. instead of using 10.40.128.61 the balancer is bound to, worker tries to call anotehr interface and fails.

      Suggestion: If user explicitly uses IP address instead of a hostname, it should be either honoured or at least explicitly configurable for the Manager-Address attribute. IMHO.
