I'm getting an exception after starting my Tomcat server with my webapp that is using coherence. In all other environments I have not gotten this error with the same tomcat and app but this new environment is a linux box with multiple interfaces.
I think it has something to do with the multicast communications which I would happily disable for now if I could but no matter what I set I still get this exception.

My tangosol-coherence-config:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<coherence>
<multicast-listener>
<address>224.1.0.0</address>
<time-to-live>0</time-to-live>
<port>2342</port>
<join-timeout-seconds>1</join-timeout-seconds>
</multicast-listener>
<unicast-listener>
<well-known-addresses>
<socket-address id="1">
<address>127.0.0.1</address>
<port>8088</port>

<logging-config>
<destination>log4j</destination>
<severity-level>4</severity-level>

So my first question is what is the correct way to disable multicast? Second question is about the exception as to what may be causing it. Thanks much.
