issue in 5.10.0

Hi,

After upgrading from 5.9 to 5.10.0, it's not as stable anymore as it used to be: after a day without any log-entries, I suddenly get 'Failed to register MBean....':

2014-06-15 21:01:55,772 | INFO | Started responder end of duplex bridge BrokerLinkXxxmmon4ToXxxxdb1 [ at ] ID:xxxmmon4-39389-1402857158840-0:1 | org.apache.activemq.broker.TransportConnection | ActiveMQ Transport: ssl:///192.168.176.84:47269

The ActiveMQ process is still there, but the JMX-listener has died without any trace.

The network-connector between this machine and Xxxmmon4 is set up by Xxxmmon4 (reason why duplex is "true"):

<networkConnector name="BrokerLinkXxmmon4ToXxxxdb1" userName="system" password="${activemq.password}" uri="static:(ssl://xxxxdb1:61616?wireFormat.maxInactivityDuration=0)?useJmx=true" dynamicOnly="false" staticBridge="true" networkTTL="3" decreaseNetworkConsumerPriority="true" duplex="true">
<staticallyIncludedDestinations>
<queue physicalName="LOCAL.ORATK"/>
</staticallyIncludedDestinations>
</networkConnector>

Any clues ?

Thanks,
Geurt
