Hi Shawn, Surfing erlang source on my phone, I=E2=80=99m guessing this is only nee= ded with erlang=E2=80=99s HIPE JIT compiler. I=E2=80=99m afk still but t= ry disabling hipe - it=E2=80=99s a default ports option toggle IIRC. If that isn=E2=80=99t sufficient I can ask over on the erlang list and r= eport back. A+ Dave
