    Error [MEM: MEM: Can't read node: {4}]

    Marcin Nowak Newbie

      Welcome

      I have problem with mod_cluster. I use jboss 7.1.1 in domain mode and mod_cluster 1.2.0.

       

      I get this error:

      [Server:server-three] 16:36:07,288 ERROR [org.jboss.modcluster.mcmp.impl.DefaultMCMPHandler] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) Error [MEM: MEM: Can't read node: {4}] sending command STATUS to proxy mint/192.168.1.17:10001, configuration will be reset

      In domain.xml - profile full and full-ha contain:

                  <subsystem xmlns="urn:jboss:domain:web:1.1" default-virtual-server="default-host" instance-id="${jboss.node.name}" native="false">

          Could be anything really.

           

          Lets look at the loadbalancer log: turn it on by (IIRC) LogLevel debug and see what will it say.

                Jean-Frederic Clere Master

                what are the error messages in error_log of htttpd?

                Note that like in the error_log of the previous case there might a few STATUS causing errors when httpd is restarted, is that the case?

                • 5. Re: Error [MEM: MEM: Can't read node: {4}]
                  Mustaq Pradhan Newbie

                  We get STATUS warning messages on error_log:

                  [warn] manager_handler STATUS error: MEM: Can't read node

                   

                  But they do not correspond to the errors we are getting to the server.log, where this is happening more frequently.

                  • 6. Re: Error [MEM: MEM: Can't read node: {4}]
                    Jean-Frederic Clere Master

                    The frequency is the same the message is the answer from httpd to the STATUS command.

                    As it is a warning probably mod_cluster works correctly, is that the case?
