I’m trying to run on an embedded device and would like the vm to only have 64 MB. I tried setting the following vm args:
-MMscs 64 -MMsco true -MMscrpm true -Musac false
I still seem to be using 103 MB according to top. What is the best way to keep the VM under a specific limit.

Aren’t those emulator flags and as such need a plus instead of a minus?

I use a plus in the arguments, but those get changed to -
when it starts beam. I copied those from top
which is why they have -
here.

Okay, I took a look at the documentation of the flags you use.
Those only affect one of the 13 allocators described in http://erlang.org/doc/man/erts_alloc.html
.
I do not think that there is a way to simulate limited RAM as you want it via arguments to the ERTS.
I think you have to use ulimit
or cgroups memory control
.
I’m not sure though, if they will set an upper bound to your process or if they will simply kill you after reaching the threshold.
