Messaging working in BlazeDS deployed on Windows Tomcat but failing in Tomcat deployed on Ubuntu

Question

I have been going round and round on this for days. I have no idea how to solve it. Everything works fine in windows but now I have to move to Ubuntu. I set up a streaming server with BlazeDS which is messaging to my clients great when my war is in tomcat 7 on windows but is failing in tomcat 7 on Ubuntu.
I see my client connect to BlazeDS on Ubuntu. The DEBUG messages print out that I have a client subscribed. It says that I have one FlexSession for an id and one client subscribed to streaming-amf. Then, a few seconds later, it says that the client sent a duplicate request "streaming-amf recieved a duplicate sreaming connection request from, FlexClient with id ... Faulting request."
Next the log files print out that there are no streaming clients for the FlexSession and no streaming clients for the endpoint streaming-amf.
This is the same software that works fine in the Windows Tomcat container but is not in Ubuntu Tomcat even though the WAR is exactly the same. In case it helps, my config files and calls are below:
messaging-config.xml
    <destination id="sp-streamingchannel">   
                       <properties>
            <network>
                <session-timeout>0</session-timeout>
                <throttle-inbound policy="ERROR" max-frequency="50"/>
                <throttle-outbound policy="REPLACE" max-frequency="500"/>
            </network>
            <server>
                <allow-subtopics>true</allow-subtopics>
                <subtopic-separator>.</subtopic-separator>
                <max-cache-size>1000</max-cache-size>
                <message-time-to-live>0</message-time-to-live>
                <durable>true</durable>
            </server>
        </properties>
            <channels>
             <channel ref="streaming-amf"/>           
            </channels>
           <adapter ref="SPStreamingAdapter"/>
           </destination>
services-conf.xml
    <channel-definition id="streaming-amf" class="mx.messaging.channels.StreamingAMFChannel">
              <endpoint url="http://localhost:8080/SP-Web-1.0/messagebroker/spamf" class="flex.messaging.endpoints.StreamingAMFEndpoint"/>
                    <properties>
                        <idle-timeout-minutes>0</idle-timeout-minutes>
                        <max-streaming-clients>150</max-streaming-clients>                      
                        <server-to-client-heartbeat-millis>5000</server-to-client-heartbeat-millis>
                              <user-agent-settings>
                      <user-agent match-on="MSIE" kickstart-bytes= "2048"  max-streaming-connections-per-session="2"/> 
                      <user-agent match-on="Firefox" kickstart-bytes="0"  max-streaming-connections-per-session="4"/>
                      <user-agent match-on="AdobeAIR" kickstart-bytes="2048" max-streaming-connections-per-session="2" />
            </user-agent-settings>
                    </properties>
          </channel-definition>
The calls in Flex:
public var channelDest:String = "http://98.193.212.138:8080/SP-Web-1.0/messagebroker/spamf";
private var channelName:String = "streaming-amf";
channelSet = new ChannelSet();
channel = new StreamingAMFChannel(channelName, channelDest);
var c:StreamingAMFChannel = new StreamingAMFChannel();
channelSet.addChannel(channel);
channel.connect(channelSet);
consumer = new Consumer();
consumer.destination  = "sp-streamingchannel";
consumer.channelSet = channelSet;
consumer.subtopic = "table." + tableID;
consumer.subscribe();
Why would this work fine on one server but fail on the other? Thanks so much for any help you can offer.
While it may not be releavnt to this question, I do have remoting working fine with BlazeDS on both systems. When my app starts, the user has to log in. All of that is done with BlazeDS and is working fine on both Win and Ubuntu. I only have a problem when it comes to streaming with BlazeDS as is shown above.
