Hi, I am load balancing between two Tomcat 6.0.20 instances with in-memory session replication using DeltaManager & StaticMember. I have a couple of application attributes which are of type ArrayList. The elements within this List is a Serializable type, but still I am getting a :
SEVERE: Unable to deserialize MapMessage. java.lang.ClassNotFoundException: com.mypackage.myclass
The class is definitely found because both instances are pointing to the same WebContent directory in the Context.xml
Also, sometimes Iget :
SEVERE: Unable to send AbstractReplicatedMap.ping message org.apache.catalina.tribes.ChannelException: Operation has timed out(3000 ms.).; Faulty members:tcp://22.214.171.124
