To add more context. The moment I saw a post from Matthias with output from his run of 
epmd, I remembered the path how I got to snoopy.

It placed something in /etc/ld.preload or set LD_PRELOAD env var. Can you check if either 
is set?

Also, can you check SELinux? I am not a SELinux expert, but check out these links:

http://etbe.coker.com.au/2008/10/29/jabber/

Or search google for "epmd selinux."

I have been trying to reproduce it on Fedora 10 32 bit but couldn't (if anyone is 
interested and has access to EC2, I tried public ami ami-2a5db943).

Like Matthias said above, it's got to be something that prevents epmd communications with 
nodes.

HTH,
Dmitriy
