Very High RAM Usage

Kingpin007 · Post by **Kingpin007** » Fri Nov 28, 2014 6:42 pm

So I just installed VestaCP on my 1GB RAM VPS. It is a preety fast server from what I have gathered but after Installing Vesta CP I am getting a very high RAM usage.
I barely banve 50MB RAM free right now.
Here is the code that is displayed when I type free-m

Code: Select all

             total       used       free     shared    buffers     cached
Mem:          1024       1006         17         34          0       1006
-/+ buffers/cache:          0       1024
Swap:            0          0          0

From what I gather the cache size is over 1000MB which is causing the slowdown.
Do you guys know any way in which I can reduce the RAM usage like drastically?

Update 1: Whenever I try to Install Wordpress or do anything this error pops up in the SSH window:
-bash: fork: Cannot allocate memory
So I am unable to do anything. Please Help me here.

And you don't have an idea what's using up all of it?

Try

top

And see.

This is the output when I type top
anyway, as I told this is related to the cache size as that is large. The rest of it is not so large. I need to reduce the cache for my server.

If it's cache - don't worry.

What the fuck do you mean by don't worry my site goes down every 2 minutes due to very high RAM usage I have to reboot the server to connect via SSH. What the fuck!?
What I am asking is to reduce the cache size so my server has some breathing room. If you can't help me then please don't fucking reply,
Bottom line: I want to reduce RAM usage (it should typically be below 100MB if I am not wrong.
