Error under heavy load: Unable to convert between org.jboss.
HI,
I create a (temporary) queue and an object to store message data to my database. This usually works well. However, whent I subject it to heavy(?) load, I get errors like this:
2005-12-21 09:31:42,477 INFO [STDOUT] [ JMSLogger:: sendMessage: Exception while sending the LogMessage Could not store message: 456 msg=455 hard NOT_STORED NON_PERSISTENT queue=QUEUE.AsynchronousLogQueue priority=9 lateClone=false hashCode=22529898; - nested throwable: (java.sql.SQLException: Unable to convert between org.jboss.mq.SpyObjectMessage and JAVA_OBJECT.)] 2005-12-21 09:31:42,477 INFO [STDOUT] org.jboss.mq.SpyJMSException: Could not store message: 456 msg=455 hard NOT_STORED NON_PERSISTENT queue=QUEUE.AsynchronousLogQueue priority=9 lateClone=false hashCode=22529898; - nested throwable: (java.sql.SQLException: Unable to convert between org.jboss.mq.SpyObjectMessage and JAVA_OBJECT.) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.pm.jdbc2.PersistenceManager.saveToStorage(PersistenceManager.java:1225) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.server.MessageCache.saveToStorage(MessageCache.java:385) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.server.MessageReference.makeSoft(MessageReference.java:311) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.server.MessageCache.validateSoftReferenceDepth(MessageCache.java:332) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.server.MessageCache.addInternal(MessageCache.java:142) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.server.MessageCache.add(MessageCache.java:112) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.server.JMSQueue.addMessage(JMSQueue.java:130) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.server.JMSDestinationManager.addMessage(JMSDestinationManager.java:402) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.server.JMSDestinationManager.addMessage(JMSDestinationManager.java:378) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.server.JMSServerInterceptorSupport.addMessage(JMSServerInterceptorSupport.java:136) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.security.ServerSecurityInterceptor.addMessage(ServerSecurityInterceptor.java:153) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.server.TracingInterceptor.addMessage(TracingInterceptor.java:270) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.server.JMSServerInvoker.addMessage(JMSServerInvoker.java:136) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.il.uil2.ServerSocketManagerHandler.handleMsg(ServerSocketManagerHandler.java:86) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.il.uil2.SocketManager$ReadTask.handleMsg(SocketManager.java:356) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.il.uil2.msgs.BaseMsg.run(BaseMsg.java:377) 2005-12-21 09:31:42,477 INFO [STDOUT] at EDU.oswego.cs.dl.util.concurrent.PooledExecutor$Worker.run(PooledExecutor.java:748) 2005-12-21 09:31:42,477 INFO [STDOUT] at java.lang.Thread.run(Thread.java:534) 2005-12-21 09:31:42,477 INFO [STDOUT] Caused by: java.sql.SQLException: Unable to convert between org.jboss.mq.SpyObjectMessage and JAVA_OBJECT. 2005-12-21 09:31:42,477 INFO [STDOUT] at net.sourceforge.jtds.jdbc.Support.convert(Support.java:449) 2005-12-21 09:31:42,477 INFO [STDOUT] at net.sourceforge.jtds.jdbc.JtdsPreparedStatement.setObjectBase(JtdsPreparedStatement.java:275) 2005-12-21 09:31:42,477 INFO [STDOUT] at net.sourceforge.jtds.jdbc.JtdsPreparedStatement.setObject(JtdsPreparedStatement.java:529) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.resource.adapter.jdbc.WrappedPreparedStatement.setObject(WrappedPreparedStatement.java:652) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.pm.jdbc2.PersistenceManager.setBlob(PersistenceManager.java:837) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.pm.jdbc2.PersistenceManager.add(PersistenceManager.java:775) 2005-12-21 09:31:42,477 INFO [STDOUT] at org.jboss.mq.pm.jdbc2.PersistenceManager.saveToStorage(PersistenceManager.java:1211) 2005-12-21 09:31:42,477 INFO [STDOUT] ... 17 more 2005-12-21 09:31:42,477 INFO [STDOUT] [ LogService::sendMessage: The message successfully sent ]
The only way to fix this seems to be to restart JBoss.
Does anyone know what is happening?
This is the code I use to test my queue:
int repeat = Integer.parseInt(request.getParameter("repeat"));
String logType = request.getParameter("logtype");
if (logType != null && logType.length() != 0) {
for (int i = 0; i < repeat; i++) {
Class c = Logger.class;
Class[] parameterTypes = new Class[] { String.class, String.class };
Method logMethod;
Object[] arguments = new Object[] { "short" + i, "long" + i };
logMethod = c.getMethod(logType, parameterTypes);
logMethod.invoke(logger, arguments);
}
}
Thank you,
L
