I would guess that this is because mmap does not work as Erlang wants it to
work. I would suggest using strace (or similar tool) to see what syscalls
are made and see what the calls to mmap returns. You could also try to
disable the Erlang memory manager and fallback to malloc by using "erl
+Meamin".
