Balancer shutdown, AS:OutOfMemoryError: unable to create new native thread -------------------------------------------------------------------------- Key: MODCLUSTER-402 URL: https://issues.jboss.org/browse/MODCLUSTER-402 Project: mod_cluster Issue Type: Bug Affects Versions: 1.2.8.Final Environment: HP-UX ia64, HP JDK 1.7 Reporter: Michal Babacek Assignee: Michal Babacek Priority: Critical Fix For: 1.2.11.Final Attachments: OOM-server.logs.zip # start Apache HTTP Server with mod_cluster # start EAP 6.3 worker 1, jvmroute: jboss-eap-6.3 # start EAP 6.3 worker 2, jvmroute: jboss-eap-6.3-2 # stop 1. # let 2. and 3. trying to contact the balancer # OOM See two detailed logs for both machines: [^OOM-server.logs.zip]. At the moment, I'm not sure it was really mod_cluster's fault, due to the JGroups messages. I have a hunch it might be linked to the new JBossWeb NIO... Assigning to myself for investigation.
