Summary: PageFile is not loaded
Key: AMQ-4214
URL: https://issues.apache.org/jira/browse/AMQ-4214
Project: ActiveMQ
Issue Type: Bug
Components: Message Store
Affects Versions: 5.7.0
Environment: Red Hat Enterprise Linux Server release 5.7 (Tikanga)
System had been up for 15 days.
The "Messages Enqueued" in the Topics tab for our topic was negative (~-63000)
The Subscriber tab showed about 14,000 in the Pending Queue Size and was not
decreasing. Messages Enqueued/Dequeued were incrementing and messages were
being delivered (this is a real-time queue).
So I deleted the Q. Then we could not recreate the Q and got the message below.
Other topics in the system appeared to be fine.
I had been doing a fair amount of testing on client error recover dropping port
connections and IP connections using the firewall so was aborting connections
frequently (though not doing a lot at once).
A number of times (due to a bug) tried to make a duplication connection to the
Q. I'm not sure exactly when the topic went haywire.
We are running over a WAN with about 30ms latency.
Can't think of anything else we were doing different than anybody else.
Here's our connection
ActiveMQConnectionFactory tcf =new ActiveMQConnectionFactory(cs);
conn = tcf.createTopicConnection();
String iName = prop.getTopicSubscriberName();
conn.setClientID(iName);
session =
conn.createTopicSession(false,TopicSession.AUTO_ACKNOWLEDGE);
topic = session.createTopic(prop.getBigDataRepositoryTopicName());
conn.start();
String sName = iName;
subscriber = session.createDurableSubscriber(topic, sName);
