You said this is a VPS, so it's going to depend on which *type* of VPS,
but mostly it's a matter of how much memory the VPS is allowed to use,
by the host system.

It looks like your VPS is limited to 1 GB (989 Mi, it says) of total
memory. If your program is coming close to that, then you may need to
talk to your VPS provider and get more memory allocated to you (which
may cost more money).

Try doubling it.
