[Building Sakai] Clustering portal chat

[Omer A Piperdi]

Actually, I have to increase the join_timeout in jGroup pbcast.GMS to 
make it work.. or start two Tomcat at the same time will work also..

I would like to know if anyone running portal chat in production?? How 
are they handling this issue. In case if you need to bring one machine 
down from cluster and put it back in later, portal chat might not work..

Thanks
Omer
