<PRE>reading the sources i have found that this crash i am trying to report
is intended behavior,
but
it happens in the middle of the SHUTDOWN procedure!
I tried to investigate how a relx's release shuts down
and i have found it is merely one call to: init:stop/0
nothing else.
the manual says:
stop() -> ok
All applications are taken down smoothly, all code is unloaded, and all
ports are closed before the system terminates. If the -heart command
line flag was given, the heart program is terminated before the Erlang
node terminates.
I end up totally clueless -- everything is rock solid yet it crashes.
maybe there is some clue in the sequence of shutting down applications?
does anything controls/defines that sequence?
