NAS box memory issues

So, I've been observing it for a while now, and I don't think there's a problem. Here's why:

• It's been powered on for around a week with no issues, and memory usage isn't significantly higher.
• I think free memory is being misreported:
  • I observed by lucky chance that the NAS box is compressing memory when it gets near full with LZMA.
  • It seems to be very lazy with deallocating memory - when a memory hog is started suddenly a lot of memory frees up.
  • Memory usage is high, but I don't think it's our code causing this, and I have seen it occaisionally drop down to around 50MB used as reported by python3-psutil, so I think this is the deallocation thing happening.
• We have not used any real amount of swap, even under "high" memory load.
• Everything seems to be running smoothly.

I think I can conclude that the software stopping a couple of weeks ago was caused by me stopping it by accident. If it happens again, I'll of course have to investigate. I could cross-compile some more tools, but I know from experience that it might be a big time drain and end up not working - if we're happy that it's working okay now I'm more than happy to leave this be.

I'm happy to let sleeping dogs lie, while at the same time keeping an eye on them.
