Hello all, long time reader, first time poster. So basically what I'm running into is that I'm having Virtual Memory Exhausted errors with various programs even though I have a 16g swap partition mounted. I've manually enabled it to try it as well. Here's some outputs to give you an idea of how my system is set up. It's a UEFI fresh install, only a couple days old.

I did just notice that it's showing 4gb less RAM than there should be (12 instead of 16, I'll be checking into that about the same time I hit submit) but as far as I can tell the system shouldn't even be worried about swap 99.99% of the time. Any ideas?
Edit: On reboot system show the full 16gb of RAM.

Could it be a hardware problem with RAM? Is there a 4 GB RAM chip in the machine that may have failed?

RAM's fine. It wasn't completely seated for some reason.

Ended up just wiping it and reinstalling. Never did figure out what the deal was with the virtual memory.
