Thanks. 2-3 days effort is quite a bit considering we'll turn around and throw it away a few weeks later, so if we can avoid it that's definitely preferable. Here's a scenario / potential test: Create a cache with say, 15 regions. Put some data in each of the regions. 2 threads. Each creates a cache then goes into a loop where it activates the 15 regions, with a 1 sec pause between activations. Start one of the threads, wait 10 secs then start the other. See if both threads complete successfully. That simulates a 10 sec staggered start of 2 servers in a cluster, with each server then deploying webapps. If that test can pass more than 90% of the time, I think it's fine for the initial beta. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3983031#...
