Out-of-memory with Tunnel and Isolating Nodes --------------------------------------------- Key: JGRP-489 URL: http://jira.jboss.com/jira/browse/JGRP-489 Project: JGroups Issue Type: Task Environment: Windows & Linux- JGroups2.5.0-beta-1 version, JDK1.5 Reporter: sampangi apparao Assigned To: Bela Ban I am new bee to the JGroups. I am trying to run demo program Draw by using TUNNEL protocol stack i.e tunnel.xml. I had two different subnets 172.x.x.x and 10.x.x.x and the GossipRouter running on 172.x.x.x. In the begining the two Draw instance are identifying each other and I can able to see drawing reflections on both nodes. After couple of minutes the two instances were isolating and another issue was identified that if we run multiple instances running on the same machine also reflecting same problem. The following error was observed during execution time And Gossip routger arguments...-bind_addr 172.16.2.49 -port 5556 336512 [TRACE] GossipRouter.mainLoop(): - REGISTER(DrawGroupDemo, 172.16.2.49:2238) 10.0.6.2:55214 closed connection; removing it from routing table 364342 [TRACE] GossipRouter.route(): - cannot find 10.0.6.2:33155 in the routing table, routing table= GROUP: 'DrawGroupDemo' logical addr=172.16.2.49:2238 (172.16.2.49:2239), 7829 ms old logical addr=10.0.6.2:33156 (10.0.6.2:52123), 9985 ms old logical addr=172.16.2.49:2329 (172.16.2.49:2330), 4907 ms old logical addr=172.16.2.49:2249 (172.16.2.49:2250), 3047 ms old ... ... 372373 [TRACE] GossipRouter.mainLoop(): - CONNECT(DrawGroupDemo, 10.0.6.2:33155) 372983 [TRACE] GossipRouter.mainLoop(): - REGISTER(DrawGroupDemo, 10.0.6.2:33155) 375280 [ERROR] Util$1.uncaughtException(): - uncaught exception in Thread[SocketThread 12,5,JGroups] (thread group=org.jgroups.util.Util$1[name=JGroups,maxpri=10] ) java.lang.OutOfMemoryError: Java heap space 375717 [TRACE] GossipRouter$SocketThread.run(): - ENGG-RAOS.us.packetmotion.com:2239 closed connection; removing it from routing table -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
