Check /etc/hosts carefully on all machines for subtle differences or 
typos. Also good to verify forward and reverse DNS are correct for all 
hosts.

Also one of the 4 hosts (foo1) does not show this problem at all. Note that all 4 hosts are same hardware and same OS (FC10) install, and have exactly same setup (as far as I can tell).
