OutOfMemory Exception in XMPP Component

                 Key: CAMEL-1467
             Project: Apache Camel
          Issue Type: Bug
          Components: camel-xmpp
         Environment: Mac OS 10.4.11, Java 1.5, Smack 3.0.4/3.1.0
            Reporter: Orton Huang
             Fix For: 2.0.0

on publishing messages lots of messages using XMPP component (layered on top of Smack 3.0.4/3.1.0
client), Out of Memory Exception occurs. 

With standard JVM settings, client runs out of memory at around 6600 messages sent. With -Xmx1024M
set, client runs out at ~110K messages sent.

Appears that on a


The server sends the message back and the messages needs to be processed on the client side
or the client will continue filling its local queue until it runs out of memory


For XmppPrivateChatProducer and XmppGroupChatProducer, need to insert chat.nextMessage() after

 public void process(Exchange exchange) {
        try {
        } catch (XMPPException e) {
            throw new RuntimeXmppException(e);
