Network Connector failures

[Michael La Budde <pa...@hotmail.com>]

I have a shared nothing master/slave configuration running under ActiveMQ 5.3.1.

Here is the networkConnector (configured only on the slave/failover node):

<networkConnector name="bridge-to-primary"
                           uri="static:(tcp://10.9.8.7:61616)"
                           dynamicOnly="false"
                           duplex="true"
                           prefetchSize="1">

On 16-February the connection between the two nodes was lost; here are some log messages:

If anyone knows why the connection between the two nodes was lost and/or has suggestions for preventing this from occurring I would be very grateful.
