IP address seems to have changed
I've just installed couchbase 2 on four VMware vm's, each vm is running rhel5 and has 4gb ram, 2 CPUs and 10gb disk space. All nodes are on the same network.
Per node I have allocated 3gb for couchbase, I've created a default couchbase bucket of 100mb, a memcached bucket of 100mb and a 2gb couchbase bucket.
My cluster has just been sitting there idle for 2 days but today I got this alert "IP address seems to have changed. Unable to listen on 'firstname.lastname@example.org'."
It is not possible for the ip to change on any of the nodes, why could I get such an alert?
