Hi all,
I have a JMS MessageListener (using MA88) listening to a single MQ queue. All this listener does is set up a QueueSender, and send the JMS message to a Weblogic queue. Thus the onMessage looks like this:
public void onMessage(JMSMessage message) {
try {
queueSender.send(message);
message.acknowledge();
} catch (Exception e) {
e.printStackTrace();
}
}
This listener runs fine for about 40 minutes. And then all of a sudden, I'll get a MQJMS1016E: an internal error has occurred. Please contact your system administrator. java.lang.OutOfMemory error.
Does anyone know why this is happening? Why would there be an OutOfMemory error, when it seems like the only thing I'm doing is queueSender.send(message)? The Using Java documentation does not have an entry for MQJMS1016, it skips it!
Any help would be much appreciated. Thanks!
Thanks,
Duke

Did you get the linked exception? It might shed some light. Also, this looks like an error that would generate an FDC file. Did you get one? If so, post the top of it.
My guesses would be that this has something to do with garbage collection not being done in a timely manner or you have a bunch of orphaned subscribers that are eating up resources. |

Hi,
thanks for the reply.
Yea I tried to print out the LinkedException, but I don't think it ever gets thrown...i.e. I think it's a runtime error or something, that suddenly just prints out:
2002.07.22 13:18:25 MQJMS1016E an internal error has occurred. Please contact your system administrator. Detail: java.lang.OutOfMemoryError
I checked the MQSeries QueueManager, and there is no FDC file, also I made sure the queue manager had the max settings for logs, i.e. 62 Primary, 61 Secondary,
The weblogic queue is not full either. Could anything in the IBM jars be causing this perhaps??
Thanks,
Duke
