[erlang-questions] Causes of - Slogan: erl_child_setup closed?

[Grant Murphy]

Hi,

I'm seeing an intermittent crash on a Ubuntu 16.04 host, Erlang version -
19.2.3.  The erl_crashdump contains "erl_child_setup closed".

Tracked the error to here
https://github.com/erlang/otp/blob/1526eaead833b3bdcd3555a12e2af62c359e7868/erts/emulator/sys/unix/sys_drivers.c#L1776,
but not entirely sure what could be causing this particular failure.

Can anybody shed some light on the likely cause of this error message?

Thanks,

- Grant
