We have 2 servers in clustered env. Server1 starts ingestion, steps/tasks of BPM workflow are executed, on Server1 and some on Server2. In middle of a BPM task execution if one server/node fails, that task is not being propagated to the other node. However, when crashed server restarts it execute the left off task. Here is the exception I see on one server when I kill the server on the other node. Again the server still running does not pick up where the 2nd server left off. 09:21:48,151 INFO [STDOUT] ==========> entering node: Decision(Content mapped to category?) 09:21:48,190 INFO [STDOUT] ==========> entering node: Node(Convert to XML) 09:21:51,742 ERROR [SocketClientInvoker] Got marshalling exception, exiting java.net.SocketException: end of file at org.jboss.remoting.transport.socket.MicroSocketClientInvoker.transport(MicroSocketClientInvoker.java:624) at org.jboss.remoting.transport.bisocket.BisocketClientInvoker.transport(BisocketClientInvoker.java:418) at org.jboss.remoting.MicroRemoteClientInvoker.invoke(MicroRemoteClientInvoker.java:122) at org.jboss.remoting.ConnectionValidator.doCheckConnectionWithLease(ConnectionValidator.java:522) at org.jboss.remoting.ConnectionValidator.run(ConnectionValidator.java:301) at java.util.TimerThread.mainLoop(Timer.java:512) at java.util.TimerThread.run(Timer.java:462) 09:21:51,763 WARN [Client] unable to remove remote callback handler: Can not get connection to server.
