Sorry about that! Service ran out of memory for some reason and I took some time to investigate.

Edit: Going to take a second hit, rebooting again to roll back a kernel upgrade that was applied yesterday.

Edit2: It's fixed properly now.

We seem to be missing about 20gb of our system memory. https://pastebin.com/teprs4qA

Let me know if you have any ideas. No it's not cache, and there's no ZFS on the system =)

Never mind, figured it out. I turned on hugepages without setting it up properly.

Look at all this beautiful free ram.

No ideas here, but memory leaks are always fun to diagnose 🙃
