Noob question: am I running out of memory?
Hello,
I ran a "free -m" and I got scared when I saw this:
root@host:/var/log# free -m total used free shared buffers cached Mem: 121 118 3 0 35 61 -/+ buffers/cache: 21 100 Swap: 236 1 235
So, my doubt is, do I have only 3 MB free, or do I have 100 MB free? Sorry for the noob question!

You have ~100MB free total. Your cache and buffers are taking up most of it.
So, the cache and buffers doesn't care at all? Will them be free if needed?
AFAIK, cache is a memory "prepared" for future needs, not used at current time.
From status above, it means that you only use 21 MB memory at the moment.
(Bad english, yay...)
They are taken currently for your applications running on the VPS in case they need them already.
