Setting for increasing MeTTa available runtime memory

I keep seeing my server crash as soon as I store more than a certain amount of data in my locally-running MeTTa hypergraph. It’s not really large volumes and the server has 32 GiB of RAM available for little more than redhat, python and running MeTTa.

The python environment that is running MeTTa has 16GiB available for storage.

Is this something that can be handled from the side of MeTTa configuration, or would you suggest a server system tweak to allocate more?

Thanks in advance for any help.
