> Hi,
> We have a setup with network bridge between two activemq, say *http-broker12 
> & http-broker21* in two different VM, where communication occurs in both ways.
> {noformat}
> <networkConnectors>
> <networkConnector name="http-broker12" 
> uri="static:(tcp://10.137.80.199:61616)" networkTTL="2"/></networkConnectors>
> {noformat}
> {noformat}
> <networkConnectors>
> <networkConnector name="http-broker21" 
> uri="static:(tcp://10.137.80.179:61616)" networkTTL="2"/></networkConnectors>
> {noformat}
> Now we are facing intermittent CPU spikes (400%) in http-broker12 broker. 
> Whereas http-broker21 works normal. 
> Could you please confirm if anything abnormal/identified bug or config issue 
> here?
> //SB
