Hi,
I've been testing the XMPP Camel component and ran into an OutOfMemoryError
after I send about 6600 packets. I have a simple client that just sends
messages one after another and the messages are roughly 4KB in size.
My client code is pretty simple:
-------------
public void sendMessages(int numOfMessages, int messageSize, String fileStr)
throws Exception {
CamelContext context = new DefaultCamelContext();
context.start();
Endpoint endpoint = context.getEndpoint(uri);
Exchange exchange = endpoint.createExchange(ExchangePattern.InOut);
Producer producer = endpoint.createProducer();
producer.start();
for (int i = 0; i < numOfMessages; i++) {
String s = fileStr;
exchange.getIn().setBody(s);
producer.process(exchange);
if ( (i+1) % 100 == 0 ) {
System.out.println("Messages Sent: " + i);
}
Thread.sleep(5);
}
producer.stop();
context.stop();
}
And the error I get is:

I've tried it with the 1.6 release and the latest 2.0 SNAPSHOT. The smack
and smackx components I use are 3.0.4. I'm also running an Openfire server
on a remote machine.
Has anyone seen this or might be able to help?
Much thanks,
Orton
