That looks like a very busy, if not overloaded, server. You need (at least) to increase the size of your swap to at least double what it is currently set at (either resize partition or add a swapfile.)
Not it doesn't, it looks like a very comfortably loaded server.
Yeah ... maybe I went too fast, in the original email "column headers" were out of kilt; my apologies. However, the example I gave of the "sandbox" shows very different results which is why I mentioned MemCache. I'm not claiming that this is the only reason, but this list is probably not the right place to discuss other checks (e.g. cat /proc/swaps, vmstat, htop) for memory management. Best - Paul

It has 2GB RAM, 3GB swap. 514MB RAM (~25%) is in use, and 2MB swap (more or less nothing) is in use. So it's got plenty of room to breathe. The key line is the one that starts with '-/+ buffers/cache' as it's the one that's ignoring cache, which is what you want to do when looking at memory usage.
Looking at one of our servers that's similarly specced and not usually too busy:
total used free shared buffers cached Mem: 2012 1885 127 0 71 1410 -/+ buffers/cache: 402 1610 Swap: 2045 0 2045
it's really very close.
So Zoe, your server is totally fine RAM-wise
