I turned on loader report generation and it ran once successfully. Since then, we've been getting

Caused by: java.lang.OutOfMemoryError: GC overhead limit exceeded

This is our sandbox (non-containerized) install and this vm has both the loader and the UI on it. It's got 8GB.

We've only allocated about 1gb for the heap.

What's a reasonable amount of memory to allocate to the loader? 3-4gb?
