I doubt it is a leak, but the VM can hold on to free memory in the
anticipation of future need which may never materialise.

So that's just ~350MB there, which means the rest of the VM process'
memory is technically free but hasn't been returned to the OS, unless
there's a leak in the VM itself.
The docs for erlang:memory/0 mention various caveats regarding the
accuracy of the reported figures, and ways to improve that accuracy,
which is something you may want to look into if you want to investigate
