Alex,
It looks like JGroups GMS (Group Membership Service) is lost. You
might have stopped and restarted a controller too fast for the other
controller to notice. So the controller excludes himself from what he
thinks is a bigger and older group than him, that's why you see a
single controller in 'show controllers'.
Hi Emmanuel
I see. Is there a workaround, or a way I could confirm that this was the
case? e.g. start one controller, wait five mins before starting the
other, or something?
I've not really been starting and stopping controllers in a rapid
fashion - I've been going from both stopped, to starting one, to
starting the other. Maybe I need a big pause before doing "show
controllers"?
You might want to try Appia instead of JGroups if the issue persists.
I'll have a look at that, thanks...
Alex
