[jboss-jira] [JBoss JIRA] Resolved: (JGRP-280) Problem with Multiplexer and state transfer

Problem with Multiplexer and state transfer ------------------------------------------- Key: JGRP-280 URL: http://jira.jboss.com/jira/browse/JGRP-280 Project: JGroups Issue Type: Bug Affects Versions: 2.3, 2.3 SP1 Reporter: Bela Ban Assigned To: Bela Ban Fix For: 2.4 Was looking at server logs from a testsuite run when I noticed something odd. We've got a 2 node cluster, node0 and node1, running the "all" config. Sequence of events: 1) node0 starts; as part of normal start of an "all" config 5 different services deploy sharing a channel (4 JBC instances + ClusterPartition) 2) Then node1 starts, and deploys the same 5 services. All is fine, incl state transfers from node0. 3) Test driver copies to node0/deploy a sar with 3 more services that use the same channel as the previous 5. This goes fine on node0, but on node1 I find a bunch of ERROR and WARN messages in the log (see below). 4) Test driver copies sar to node1/deploy. The 3 services deploy on node1 without problem; no further error messages. 5) The test itself passes fine; I just happened to see the following in the logs. Following are the messages. Looks like 1) node1 gets a state transfer request for the BadPartition-TreeCache service, which AFAICT it shouldn't. 2) The Multiplexer throws an exception on the request instead of logging a WARN, and 3) when the Multiplexer gets a view for a service it doesn't have, it logs a WARN, which should probably be an INFO, as its not a sign of something wrong in this case. 2006-08-20 19:55:00,593 ERROR [STDERR] java.lang.IllegalArgumentException: didn't find service with ID=BadPartition-TreeCache to fetch state from 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.mux.Multiplexer.handleStateRequest(Multiplexer.java:490) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.mux.Multiplexer.up(Multiplexer.java:260) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.JChannel.up(JChannel.java:1082) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.stack.ProtocolStack.up(ProtocolStack.java:377) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.stack.ProtocolStack.receiveUpEvent(ProtocolStack.java:393) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.stack.Protocol.passUp(Protocol.java:538) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.protocols.pbcast.STATE_TRANSFER.requestApplicationStates(STA TE_TRANSFER.java:308) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.protocols.pbcast.STATE_TRANSFER.up(STATE_TRANSFER.java:137) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.stack.Protocol.receiveUpEvent(Protocol.java:488) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.stack.Protocol.passUp(Protocol.java:538) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.protocols.FRAG2.up(FRAG2.java:197) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.stack.Protocol.receiveUpEvent(Protocol.java:488) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.stack.Protocol.passUp(Protocol.java:538) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.protocols.FC.up(FC.java:344) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.stack.Protocol.receiveUpEvent(Protocol.java:488) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.stack.Protocol.passUp(Protocol.java:538) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.protocols.pbcast.GMS.up(GMS.java:753) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.stack.Protocol.receiveUpEvent(Protocol.java:488) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.protocols.pbcast.GMS.receiveUpEvent(GMS.java:773) 2006-08-20 19:55:00,593 ERROR [STDERR] at org.jgroups.stack.Protocol.passUp(Protocol.java:538) 2006-08-20 19:55:00,609 ERROR [STDERR] at org.jgroups.protocols.VIEW_SYNC.up(VIEW_SYNC.java:154) 2006-08-20 19:55:00,609 ERROR [STDERR] at org.jgroups.stack.Protocol.receiveUpEvent(Protocol.java:488) 2006-08-20 19:55:00,609 ERROR [STDERR] at org.jgroups.stack.Protocol.passUp(Protocol.java:538) 2006-08-20 19:55:00,609 ERROR [STDERR] at org.jgroups.protocols.pbcast.STABLE.up(STABLE.java:258) 2006-08-20 19:55:00,609 ERROR [STDERR] at org.jgroups.stack.Protocol.receiveUpEvent(Protocol.java:488) 2006-08-20 19:55:00,609 ERROR [STDERR] at org.jgroups.stack.Protocol.passUp(Protocol.java:538) 2006-08-20 19:55:00,609 ERROR [STDERR] at org.jgroups.protocols.UNICAST.up(UNICAST.java:224) 2006-08-20 19:55:00,609 ERROR [STDERR] at org.jgroups.stack.Protocol.receiveUpEvent(Protocol.java:488) 2006-08-20 19:55:00,609 ERROR [STDERR] at org.jgroups.stack.Protocol.passUp(Protocol.java:538) 2006-08-20 19:55:00,609 ERROR [STDERR] at org.jgroups.protocols.pbcast.NAKACK.down(NAKACK.java:428) 2006-08-20 19:55:00,609 ERROR [STDERR] at org.jgroups.stack.Protocol.receiveDownEvent(Protocol.java:517)
