I tried to set up Sequoia replication between controllers via JGroups (TCP/TCPPING with fixed IPs for a list of controllers). I was able to transfer dumps all right. Controllers see each other and everything seems to be good until I start using the database for updates. One of the controllers gives a WARN about "not all backends" somewhere, while the other gives an INFO message about "unrecognized response from controller (null)". I realize the description is vague and I will follow up with exact error messages, but I have a suspicion that my JGroups configuration was not ( or far from) perfect. Is there a verified JGroups TCP config for sequoia? I could use appia, but I got an impression that appia requires a dedicated gossip server, if I want to use TCP and such server becomes a single point of failure. I wonder if anyone could provide guideance here? Anton
