VPS server always uses upto 90% of ram

[rainy]

Hi everyone!

I have a vps that has 2 gb of ram. i install ubuntu 14.04 64bit in there and then install sentora
i only have 1 website run on sentora

My problem is my vps use up to 90% of ram, i have another vps running the same configuration too but it just take like 300mb of ram, while this one take up like 1.5 - 1.8 gb

I try to restart it and watch htop, it stays within 300mb of ram for 10 mins then suddenly it races to 1.5 gb like crazy, eventhough at that time no one do anything, not even access the site

Have any one face any problem like that before?

Is there a way to fix it?

Any suggestions is highly appriciated!

Use the top command to check which process uses most RAM.

Are you using the "free" command?
Are you sure this isn't your issue?

i did use htop and free -m to monitor, but i just found out ( i'm still monitoring it) if i change the sentora theme back to it's default then the ram seem to be normal again ( aroudn 300 mb) but if i use zentora (very attractive theme) then it's gona kill my Ram again

Anyone has the same issuse?

Using my own theme:

Code:

root@server1:~# free -m
            total       used       free     shared    buffers     cached
Mem:           490        253        236          5         17        118
-/+ buffers/cache:        116        373
Swap:            0          0          0

Using Zentora:

Code:

root@server1:~# free -m
            total       used       free     shared    buffers     cached
Mem:           490        267        222          6         18        122
-/+ buffers/cache:        126        363
Swap:            0          0          0

Using default:

Code:

root@server1:~# free -m
            total       used       free     shared    buffers     cached
Mem:           490        273        216          6         18        123
-/+ buffers/cache:        131        358
Swap:            0          0          0

So yes, the RAM drops a little when using the default theme, but that 20-30MB shouldn't matter....

The differences are hardly theme related.
These are normal variations...

Yes, but when I use Sentora's default theme, I still only use 1/4 of my total RAM. He says 1.5-1.8 of his 2GB. That's not regular. Are you running something next to Sentora? Teamspeak, gameserver, VPN, whatever?

Unless he decides to post more information we can't do anything more than to guess.
I'm not sure about what values he read...

Anyways, unles the theme is really bad coded, it should not make difference, almost none if any.

rainy can you post the free -m results (like Rick did)?

Also post the htop ones.

Actually, I couldn't image how a theme could ever use a shitload of RAM. Only for gettings the file and transmitting it. The file itself is compiled by the browser, client-side... 

As you've said, he has to give more info. Else we are not able to help you.

Hi everyone! first of all thank you for your support!

As you can see, i reboot it and after less than 2 hours it races to 1622 MB of ram.

Please give me some ideas to troubleshoot it, if u need some logs please let me know ( please tell me which command to get the log too! , coz im tottally new in ubuntu and sentora)

Thank you!
