setup a combination of mod_cluster 1.2.0.Final, JBossAS 7.1.1.Final and OpenJDK 1.6 on CentOS 6.2So far it seems like JBoss can't automatically discover the mod_cluster server.My steps:0. Disable firewall1. Download and install mod_cluster standalone. No changes in httpd.conf2. Run: sudo /opt/jboss/httpd/sbin/apachectl start3.

I am using apache (ver 2.2.22) with mod_cluster(ver 1.2.0) for load balancing. When I bring up both JBoss I could see the cluster view updated with both the nodes. But, I am getting the following error in Jboss: ERROR [org.jboss.modcluster.mcmp.impl.DefaultMCMPHandler] (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) Error [MEM: io error sending MEM: Can't read node: {4}] sending command STATUS to proxy 127.0.0.1/127.0.0.1:6666, configuration will be reset In Apache logs, here is what I have: [notice] Parent: child process exited with status 255 -- Restarting.

I could figure it out from the windows event logs. Here is what I have in the event log: Faulting application name: httpd.exe, version: 2.2.22.0, time stamp: 0x4faff1ba Faulting module name: mod_proxy.so, version: 2.2.21.0, time stamp: 0x4f3494b7 Exception code: 0xc0000005 Fault offset: 0x0000000000003115 Faulting process id: 0x12b4 Faulting application start time: 0x01cf4735c4635dbb Can anyone please help me out with how to solve this? Do I have to use a different versio
pure IPv6 setupAgile Board ExportXMLWordPrintable Details Type: Bug Status: Closed (View Workflow) Priority: Critical Resolution: Out of Date Affects Version/s: 1.2.1.Final Fix Version/s: None Component/s: None Labels: as7 eap6 ipv6 mod_cluster Environment: RHEL 6 x86_64, pure IPv6, Apache/2.2.21 (Unix) mod_cluster/1.2.1.Final Description As a follow up on JBPAPP-9195 mod_cluster: HTTP 503 on node shutdown with pure IPv6 setup I have tried this mod_cluster + httpd bundle featuring Apache/2.2.21 (Unix) mod_cluster/1.2.1.Final (unlike in JBPAPP-9195 where we used Apache/2.2.17 (Unix) DAV/2 mod_cluster/1.2.1.Beta2) mod_cluster-1.2.1.Final-linux2-x64.tar.gz the result is surprising: Very frequent HTTP 404 errors on node shutdown. Http client I have a curl client issuing requests to [2620:52:0:105f::ffff:c]:8888/SessionTest/hostname periodically, delay being 1 s. Note that there is always a new session for each request (no JSESSIONID stuff anywhere). There are two nodes I switch off and on randomly, always giving enough time so as the starting one may take off safely.
