Getting critical Memory error quite often

We have a linux machine with 32GB RAM but tiger graph keeps showing critical memory error , and when looking at graph studio admin portal, it shows only 8 GB in consumption. Is there a way to check hy TG is only limiting to 8 GB and starts throwing critical memory. How to make it use most of 32GB memory available.

Refer attached screen shot for memory consumption.

Check if something on the machine is limiting TG processes. What Linux distro and are you using native installation or virtualization deployment?
