This question already has an answer here:

I'm having some issues with my VPS Ve, right now I have two sites running with PHP (one of them with Wordpress), a few days ago the RAM usage rose above 100%, strange thing is I made no changes.

RAM memory is increasing progressively in the MediaTemple statics panel, what I don't understand is why do I have so much difference between the data I get from the console.

My Setup:

  • nginx
  • php-fpm
  • apc
  • mysql
  • Ubuntu 10.04
  • 4GB RAM (VPS)


Free -m:

total      used    free  shared buffers  cached
Mem:       6348    2854    3494    0       0       2403
-/+ buffers/cache:   450       5897
Swap:    0     0       0

Could you guide me so I may know what is it that is using up memory?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Is something actually wrong or is this just curiosity. – David Schwartz Aug 17 '13 at 4:47
Thanks for answering. My only problem is that MT statics are showing that I'm consuming more than 110% of memory. And I'm worried that it might be something I could be penalized for. – Pablo Aug 17 '13 at 7:19

It's cache, don't worry, it's normal and it's good:

Your system is "using" 450 MB of RAM :) Cache will be flushed and applications will be able to use freed memory when needed. Why to waste memory? Let's use it for cache.

Here's good script for you

I installed the script that you gave me, thanks, result threw 501.5MB which is a lot lower than the 4GB that what my hosting provider is showing. I don't get why RAM memory statistics on the server keep rising progressively until they're over 110%. Thanks!! :D – Pablo Aug 17 '13 at 7:23
