BEAM VM consumes big amounts of memory VIRT vs :erlang.memory(:total)

Does that reply by one of Erlang’s maintainers help?

Elixir / Erlang docker containers RAM usage on different OS's / Kernels

Erlang on most Unixes allocates a lot of virtual memory at startup, but only uses a small amount of it. If your OS physically reserves all virtual memory (or limits memory usage by looking at virtual memory) you can change how much is reserved by Erlang though the +MIscs switch.
