[infinispan-issues] [JBoss JIRA] Updated: (ISPN-762) possible deadlock during start of 3 HotRod Server nodes

[ https://jira.jboss.org/browse/ISPN-762?page=com.atlassian.jira.plugin.sys... ] Jacek Gerbszt updated ISPN-762: ------------------------------- Description: While starting 3 HotrodServer nodes at the same time, I receive an exception: 2010-11-08 13:21:11,081 ERROR [org.infinispan.remoting.rpc.RpcManagerImpl] (InfinispanServer-Main) unexpected error while replicating org.infinispan.manager.NamedCacheNotFoundException: Cache: ___hotRodTopologyCache at org.infinispan.remoting.InboundInvocationHandlerImpl.handle(InboundInvocationHandlerImpl.java:72) at org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher.executeCommand(CommandAwareRpcDispatcher.java:176) at org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher.handle(CommandAwareRpcDispatcher.java:148) at org.jgroups.blocks.RequestCorrelator.handleRequest(RequestCorrelator.java:575) at org.jgroups.blocks.RequestCorrelator.receiveMessage(RequestCorrelator.java:486) at org.jgroups.blocks.RequestCorrelator.receive(RequestCorrelator.java:362) at org.jgroups.blocks.MessageDispatcher$ProtocolAdapter.up(MessageDispatcher.java:771) at org.jgroups.JChannel.up(JChannel.java:1453) at org.jgroups.stack.ProtocolStack.up(ProtocolStack.java:887) at org.jgroups.protocols.pbcast.FLUSH.up(FLUSH.java:483) at org.jgroups.protocols.pbcast.STREAMING_STATE_TRANSFER.up(STREAMING_STATE_TRANSFER.java:265) at org.jgroups.protocols.FRAG2.up(FRAG2.java:188) at org.jgroups.protocols.FC.up(FC.java:494) at org.jgroups.protocols.pbcast.GMS.up(GMS.java:888) at org.jgroups.protocols.pbcast.STABLE.up(STABLE.java:234) at org.jgroups.protocols.UNICAST.up(UNICAST.java:309) at org.jgroups.protocols.pbcast.NAKACK.handleMessage(NAKACK.java:813) at org.jgroups.protocols.pbcast.NAKACK.up(NAKACK.java:671) at org.jgroups.protocols.BARRIER.up(BARRIER.java:120) at org.jgroups.protocols.FD_ALL.up(FD_ALL.java:177) at org.jgroups.protocols.FD_SOCK.up(FD_SOCK.java:270) at org.jgroups.protocols.MERGE2.up(MERGE2.java:210) at org.jgroups.protocols.Discovery.up(Discovery.java:283) at org.jgroups.protocols.PING.up(PING.java:67) at org.jgroups.protocols.TP.passMessageUp(TP.java:1009) at org.jgroups.protocols.TP.access$100(TP.java:56) at org.jgroups.protocols.TP$IncomingPacket.handleMyMessage(TP.java:1549) at org.jgroups.protocols.TP$IncomingPacket.run(TP.java:1531) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) I think the problem is that ___hotRodTopologyCache is defined to late. When the default cache is started in AbstractProtocolServer.start() the cluster is up and running - ready to receive the replication messages. But unfortunately ___hotRodTopologyCache is not yet defined, which is done a few lines later in HotRodServer.addSelfToTopologyView(). Simply moving one line of code from addSelfToTopologyView to start method, as shown in the attachement, would solve this problem. But it's not the end of story. Even though all the caches are defined in the right place, there is still a problem during starting 3 nodes at a time.
