    Immediate eviction of a dead worker




      Our setup is as follows :

      Apache 2.2.22

      Mod_Cluster 1.2.6 Final

      This connects to two Tomcat 7.0.40 instances.


      If I do an orderly shutdown of the tomcat instance, the next request is sent to the live node, as expected.

      However, if I kill the tomcat process abruptly, the requests are still attempted to the now dead host. I see the ajp connection failing, and after a while the connection fails over.

      Is there a way of forcing an immediate eviction of a dead worker ?


      Config :

      <VirtualHost *:6666>

              MaxKeepAliveRequests 0

              AdvertiseFrequency 5

              AdvertiseSecurityKey mySecurityKey

              <Location />

                  Order deny,allow

                  Allow from 127.0.0


              ServerAdvertise On




      Further info :

      When the hosts goes away, mod_cluster manager reports the host as NOTOK, and the apache logs show :

      [Fri Sep 27 10:20:51 2013] [error] proxy: ajp: disabled connection for (196.xx.xx.xx)

      [Fri Sep 27 10:20:56 2013] [error] proxy: CLUSTER: (balancer://liferay). All workers are in error state for route (quack)
