Hi Yair,

Here is the spmonitor report:


I add the first node at T+0, the second one at T+15 seconds, upon which
they sync up and all is fine. Then I add the third node at T+46 seconds,
and they never manage to sync.

I've left it for around 7 minutes after adding the last node, to no

Let me know any further information you would like, or whether you'd
like SSH access to this cluster to start debugging. If it helps speed
things up, you can add me on Skype, I'm luke.marsden.

I'll be here all day :-)

Best Regards,
Luke Marsden
