I'm setting up a JBoss Cache cluster with two servers. Each server runs a cache
instance. Each instance asynchronously replicates to the other using UDP mcast. When both
servers were running, they kept logging the errors below. I've tried the Probe test
and the LargeState. Both worked well. I also checked to make sure mcast was configured on
both servers. Anything else should I look into? Thanks!
