--------------------------------------------------------------
I have a cluster of jboss servers running behind a vip. The session cache uses infinispan and is configured below:


            <cache-container name="web" aliases="standard-session-cache" default-cache="sso">
                <transport lock-timeout="60000"/>
                <replicated-cache name="sso" mode="SYNC" batching="true">
                    <file-store/>
                </replicated-cache>
            </cache-container>



I am seeing the following error show up sporadically. It does not happen every request but when it happens the request fails.

Is this a known issue? I've seen some similar JIRA's open but no solutions.
