[erlang-questions] init:stop() not working?
Mon Dec 17 15:09:57 CET 2012
Thanks for the input. We don't have an application structure, just loading
modules freely. The thing is that only some of the vms get in this state,
so my first reaction was that it's something nondeterministic, like hanging
on some socket or something like that. But it happens deterministically
enough (the same kind of instance gets zombified) to make that less
