Hi,
</div><div><br></div><div>I've found a but that if Erlang is installed in a path with spaces then _epmd_ fails to start when started automatically by _erl_. You can still start epmd manually.</div><div>

<div><div>In the Mac is quite common to have User home folders in path with spaces. I've found this while trying to create an Erlang release and distribute it via inside a Mac.app</div><div><br></div>
<div>The bug happens in R15B01 so I guess it also appears in earlier versions.</div><div><br></div><div>Also perhaps if epmd is not running for whatever the reason maybe Erlang could give a more meaningful error.</div><div>
