Are all Tomcat instances in the cluster running the same version of
Tomcat? Are all instances running the same version of your application?
Do you have any idea which class is being deserialized when this
happens? A serialVersionUID of "1" or "2" is a bit odd, so I'm
guessing that's a class from your own application.

Hi,
It turned out to be a multicast setup problem.
We had a tomcat cluster already running in the LAN with a defualt
cluster setting(uncomment SimpleTcpCluster.)
When I created this new cluster, I used the defualt setting as well, so
there was a multicast collision.
After I added another address of McastService in new cluster server.xml,
the problem solved.
Thanks.
JC
