I had the same error due to lackness of the /var/run/zorp directory. 
At least with my configuration zorp needed to do an udp socket there.

Try to run the two zorp instances with strace as follows:

strace /usr/lib/zorp/zorp --as intern -B 1.1.1.1 --verbose 3 -p 
/path/to/your/instances-config -l >& zorp.log

Then search for your error, and hopefully you will find what's wrong 
there.

Are you sure about the autobind syntax? We are using "-B 1.1.1.1", from 
the usage info it would seem that you should use "--autobind-ip 1.1.1.1"

We are now using one of the server's ip, and I didn't observe any 
difference from using a dummy interface.

Hope it helps,
