[Design of JBoss Portal] - Re: portal clustering problem when using optimistic locking
by prabhat.jha@jboss.com
With jboss cache version 1.4.1.SP8 (http://repository.jboss.com/jboss/cache/1.4.1.SP8.patch02-brew), I do not have problem accessing a portal page. Hence this certainly fixes this problem. However, I see some errors with 2 and 3 nodes:

Do I need to update jgroups library for this cache version? With 4-node cluster, I am getting very bad performance. I will look into that.
