I'd try putting all hostnames in /etc/hosts. Also, can you post ping times
between each host ?
They are in /etc/hosts.

As said before, I don't think there's a problem with the LAN. Trust me, I
would know about it :)

Ah... are these nodes separated by a WAN? Synchronous

geo-replication instead
(which I've not tested)
No, it's a 1 Gbps LAN. The other "site" is within LAN-range.
