</div>A shot in the dark: have you tried adding something like this:<br><br> net_kernel:start(['<a href="mailto:eunit_test_node@127.0.0.1">eunit_test_node@127.0.0.1</a>', longnames])<br><br></div>before performing `slave:start(..)`? I remember that occasionally the issue was that `net_kernel` was not running. Also make sure you have `epmd` running in the OS.</div>

Maybe i'm missing something, but I think that slaves nodes are getting right the path to find all required beams. All slaves are initialized using:<br>
<div>Args = " -pa apps/*/ebin deps/*/ebin -setcookie secret -rsh ssh",<br>
</div> In fact when I execute cluster_test:cluster_formation() works fine.<br>

What's the difference to use -pz from -pa?<br>

Thank you!<br>
