So I just upgraded Seam and I didn't encounter this error but I am still required to login again after the active cluster instance becomes disabled. My session data appears to be replicated yet Seam requires a new login after the failover. Can someone, if anyone, provide some information on Seam in a clustered environment it is giving me headaches at the moment. S.D.
