Generally things are working, except for an intermittent NPE associated with accessing the PList in the FileCursor, such as the following. This apparently results in a lost message.
I am currently working under the assumption this is related to the known issue https://issues.apache.org/jira/browse/AMQ-3434. Does this seem correct? Is there an estimate of when this fix might be available? 2011-09-03 09:17:40,166 ERROR [cursors.FilePendingMessageCursor] [] : Caught an IO Exception getting the DiskList 7_PendingCursor:S_TableQueue_CHF java.lang.NullPointerExceptionnull at org.apache.activemq.store.kahadb.plist.PListStore$1.execute(PListStore.java:212)null at org.apache.kahadb.page.Transaction.execute(Transaction.java:728)null at org.apache.activemq.store.kahadb.plist.PListStore.getPList(PListStore.java:208)null at org.apache.activemq.broker.region.cursors.FilePendingMessageCursor.getDiskList(FilePendingMessageCursor.java:442)null at org.apache.activemq.broker.region.cursors.FilePendingMessageCursor.flushToDisk(FilePendingMessageCursor.java:423)null at org.apache.activemq.broker.region.cursors.FilePendingMessageCursor.onUsageChanged(FilePendingMessageCursor.java:381)null at org.apache.activemq.usage.Usage$1.run(Usage.java:268)null at java.util.concurrent.ThreadPoolExecutor$ Worker.runTask(ThreadPoolExecutor.java:886)null at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908)null at java.lang.Thread .run(Thread.java:619)null Exception in thread "Usage Async Task" java.lang.RuntimeException: java.lang.NullPointerException at org.apache.activemq.broker.region.cursors.FilePendingMessageCursor.getDiskList(FilePendingMessageCursor.java:445) at org.apache.activemq.broker.region.cursors.FilePendingMessageCursor.flushToDisk(FilePendingMessageCursor.java:423) at org.apache.activemq.broker.region.cursors.FilePendingMessageCursor.onUsageChanged(FilePendingMessageCursor.java:381) at org.apache.activemq.usage.Usage$1.run(Usage.java:268) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) Caused by: java.lang.NullPointerException at org.apache.activemq.store.kahadb.plist.PListStore$1.execute(PListStore.java:212) at org.apache.kahadb.page.Transaction.execute(Transaction.java:728) at org.apache.activemq.store.kahadb.plist.PListStore.getPList(PListStore.java:208) at org.apache.activemq.broker.region.cursors.FilePendingMessageCursor.getDiskList(FilePendingMessageCursor.java:442) ... 6 more -- View this message in context: http://activemq.2283324.n4.nabble.com/AMQ-5-5-non-persistent-messages-not-processed-counted-as-in-flight-tp3776808p3796511.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
