Nope, it's not related.

- failed to start slave node in test.

All of the failures has the same cause, namely it cannot start a slave 
node. This is probably due to some faulty network configuration.

Try starting two erlang nodes using -sname a, -sname b and then pinging 
them, i.e:
(a@<your-host>)1> net_adm:ping(b@<your-host>).
