I seem to have ~4.2 TB of something cached on my well-loved and used Debian fileserver. I don't notice any problems, but this is really strange. Nothing like this happens on my main box.
In yellow is everything that holds bytes (disc and RAM) and in red is the mysterious 4.2TB of "cached."
While I was typing this up, I checked again, and the "cached" went down 6 orders of magnitude to about 8900 kB, and it's rising slowly and irregularly.
