[erlang-questions] Need help with the error dump - erl_child_setup closed

according to 19.0 release notes (http://erlang.org/download/

"OTP-13088 Application(s): erts The functionality behind erlang:open_port/2
when called with spawn or spawn_executable has been redone so that the
forking of the new program is done in a separate process called
erl_child_setup. ..."

and the ERTS release notes mentions a bug fix in 19.1 (

"Fix a rare race condition in erlang:open_port({spawn, ""}, ...)
 that would result in the erl_child_setup program aborting and
 cause the emulator to exit.

 Own Id: OTP-13868"


so maybe you've hit this race bug. This may or may not be of any use for
you :)
(Upgrading to 19.1 might help)
