Transport fails IOException (Unknown data type: 0) --------------------------------------------------
Key: AMQ-2619 URL: https://issues.apache.org/activemq/browse/AMQ-2619 Project: ActiveMQ Issue Type: Bug Affects Versions: 5.3.0 Reporter: Goran Pugar In setup with 2 brokers connected with ConduitBridge, we have a problem with network connector which is ocasionally disconnected because of java.io.IOException (Unknown data type: 0) on other node - stack trace attached below. Network connector reconnects after some time, but we have some message loss since we use syncSend=false on queues. {code} 10:33:32,539 DEBUG [Transport ] Transport failed: java.io.IOException: Unknown data type: 0 java.io.IOException: Unknown data type: 0 at org.apache.activemq.openwire.OpenWireFormat.tightUnmarshalNestedObject(OpenWireFormat.java:441) at org.apache.activemq.openwire.v5.BaseDataStreamMarshaller.tightUnmarsalNestedObject(BaseDataStreamMarshaller.java:126) at org.apache.activemq.openwire.v5.MessageMarshaller.tightUnmarshal(MessageMarshaller.java:83) at org.apache.activemq.openwire.v5.ActiveMQMessageMarshaller.tightUnmarshal(ActiveMQMessageMarshaller.java:66) at org.apache.activemq.openwire.v5.ActiveMQObjectMessageMarshaller.tightUnmarshal(ActiveMQObjectMessageMarshaller.java:66) at org.apache.activemq.openwire.OpenWireFormat.doUnmarshal(OpenWireFormat.java:366) at org.apache.activemq.openwire.OpenWireFormat.unmarshal(OpenWireFormat.java:279) at org.apache.activemq.transport.tcp.TcpTransport.readCommand(TcpTransport.java:210) at org.apache.activemq.transport.tcp.TcpTransport.doRun(TcpTransport.java:202) at org.apache.activemq.transport.tcp.TcpTransport.run(TcpTransport.java:185) at java.lang.Thread.run(Thread.java:619) 10:33:32,541 DEBUG [TransportConnection ] Stopping connection: /192.168.0.2:40408 10:33:32,542 DEBUG [TransportConnection ] Stopped transport: /192.168.0.2:40408 10:33:32,542 DEBUG [TransportConnection ] Cleaning up connection resources: /192.168.0.2:40408 10:33:32,542 DEBUG [AbstractRegion ] mgw.broker01 removing consumer: ID:node2-42470-1264024561798-1382:0:1:1 for destination: topic://ActiveMQ.Advisory.Consumer.> 10:33:32,561 DEBUG [TransportConnection ] Connection Stopped: /192.168.0.2:40408 {code} -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
