[erlang-questions] Causes of - Slogan: erl_child_setup closed?
Mon Feb 20 08:38:08 CET 2017
You get that message if the erl_child_setup process for some reason
terminates. The erl_child_setup process is responsible for doing the setup
of any external port program that gets started, i.e. os:cmd/open_port.
The only "normal" reason that I have found so far for erl_child_setup to
exit is if the Linux OOM killed decides to terminate it. Besides that all
terminations should be considered bugs in erl_child_setup.
Do you have any core file from erl_child_setup? Any printouts to stderr?
