Hi,

We are having two JBoss 4.0.4 on the same machine in a cluster in active-active 
way.With active active cluster, we are running into serializable exceptions 
because of session replication and are experiencing unacceptable latency. So we 
have decided to use cluster just for fail over and not for session replication.

I know that our code has objects that are not implementing serializable 
interface but at this stage we cannot afford to change it. we also feel that we 
do not have to change it if we are not going for session relication.

After reading some of the  posts here and refering couple of other documents, I 
found out that change of cache mode attribute to local should turn off sessio 
replication. Also we are using modjk, so I commented out the following

instant
2000

and 

jboss.cache:service=TomcatClusteringCache
      
jboss:service=TransactionManager

Even after making these changes, I still see serializable exceptions. 
I am not sure if session replication is happening or not. We do not want 
session replication, please advice me on the changes that I need to make to 
turn off session replication...Thanks
