I'm having intermittent failures when I deploy to a cluster. I see the
war file sent to slave nodes but it then becomes zero size. It happens
on different nodes and not all the time.
Upon failure, Master node .out shows
SEVERE [Catalina-utility-1]
org.apache.catalina.ha.tcp.SimpleTcpCluster.send Unable to send message
through cluster sender.
org.apache.catalina.tribes.ChannelException: Send failed,
