Exception in thread "main" java.lang.OutOfMemoryError: Java heap space running with a Multiplex channel ------------------------------------------------------------------------------------------------------- Key: JGRP-599 URL: http://jira.jboss.com/jira/browse/JGRP-599 Project: JGroups Issue Type: Bug Affects Versions: 2.5.1 Environment: Linux Reporter: Rita Patel Assigned To: Bela Ban Priority: Critical My test application goes out of memory after about running for ~85-90 mins. (with 2.5.1 groups released version) Test app just creates a multiplex channel ( uses UDP protocol) and broadcast the message. (I only have one member in cluster for testing) Would you please take a look at the test code and let me know if I am not implementing multiplex channel correctly. public class TestJGroups { static Logger log = Logger.getLogger(TestJGroups.class); public static void main(String[] args) throws Exception{ BasicConfigurator.configure(); Logger.getRootLogger().setLevel(Level.DEBUG); Logger.getLogger("org.jgroups").setLevel(Level.DEBUG); log.info("log4j is set up correctly."); log.info("this thread iD: "+Thread.currentThread().getId()); Channel mulplexChannel2 = createMultiplexerChannel("Service_Registry"); log.info("I have created mux channgel"); while(true){ //Thread.sleep(10000); mulplexChannel2.send(new Message(null,null,"Hello world".getBytes())); log.info("after sending message to all"); //DaemonThreadUtility.printCurrentDaemonThreads(log.getName()); } } private static Channel createMultiplexerChannel(String channelID) throws Exception{ String CFG = "/users/rpatel/sandbox/stacks.xml"; String STACK_NAME = "udp"; ChannelFactory factory = new JChannelFactory(); File configFile = new File(CFG); Channel channel = null; factory.setMultiplexerConfig(configFile); channel = factory.createMultiplexerChannel(STACK_NAME, channelID); log.debug("after createing multiplexer channel"); //DaemonThreadUtility.printCurrentDaemonThreads(log.getName()); channel.connect(channelID); log.debug("after connecting multiplexer channel"); //DaemonThreadUtility.printCurrentDaemonThreads(log.getName()); return channel; } } -- 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
