Check the "Leave at least" setting. I think it defaults to something really small, like 200MB. Should be 4-8 GB depending on how you work. Render slaves can have less, but workstations tend to have more applications and services running.
I don't have any issues with purging manually or automatically. It just works for me. That said, I don't know if there's anything strange in your comp, or how well you manage your cache usage. There could be a buggy setup that you might see a lot but no one else does because they don't use those tools in that way.
Fusion uses a lot of RAM. Always has, even before it was 64 bit. That's part of what allows it to be so much faster than other applications. If you're using a desktop, 32GB isn't enough RAM for general purpose use. If you're using a laptop, I wouldn't expect to be doing more than very simple or very short comps. I advise users to run a minimum of 128GB for Fusion workstations. 256GB is the sweet spot. I've done stereoscopic 4K HFR shots on 32GB, but I would not recommend it, not when RAM is so cheap these days.
