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.

total used free shared buffers cached

Swap: 2997 2 2995
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
