i have 2 load balanced, clustered machines with 1 stateful session bean whose clustering is turned on. Experimenting between the machines, about 1 out 7 times the stateful session bean will fail to cluster properly. It loses the sateful session bean when i shutdown the jboss app server on one machine. Is this a known problem with stateful session ejb3.0 beans? for the most part it clusters, but it's clustering is much more unreliable than http session clustering.
What version of EJB3 and what cache type please?
