I have overloaded the server, why?

danielpz · May 4th 2013

hello friends, I have a dilemma rather rare, day before yesterday I had my server with 223 mb of ram free, and only today I have 8 MB of free RAM, and I have not made any change in these days, I have not added web any more, nor have I removed anything ...,,

That could be what is causing the overload on my server?

I leave the report of "ps aux"

please help!, all actions performed as deleting a domain, or suspend a domain, etc., it takes way too, and it does the I-MSCP, I guess that is overloading ... : (

Note: I have the plan "starter" of intovps, http://www.intovps.com/plans.html

[size=medium]Update!!!:[/size]

I have all my website stop:

and this is my memori ram:

this memory usage normal?

Hello ;

The information you are providing are not sufficient.

7.3 Mib free doesn't necessarily mean that you lack of memory. You must provide us the result of the following command :

Code

$ free -m

For instance, on my server, I can see

Code

nuxwin@dev:~$ free -m
total used free shared buffers cached
Mem: 7881 7530 350 0 282 3221
-/+ buffers/cache: 4026 3854
Swap: 15623 6 15617
nuxwin@dev:~$

Here, 350 Mo free doesn't mean that I have only 350 Mo free. You must take the cached memory value too. So here, I've 3854 Mo free in reality.

For the rest, you must provide us the logs.

Thank you for using i-MSCP.

I have this,,,

why it is overloaded?

**c0urier** · May 9th 2013

Are you still running the download script as you've posted in another thread?

If yes, it could be using a lot of memory to spawned PHP processes to handle downloads/uploads.
An advice, if you are going to run a download site, use a dedicated server.

No!, as no one responded on the other thread just remove the discharge system

Thank you for answering ..

this is already way too weird, I changed all my domains DNS to point to my shared hosting "Godaddy", now you are not on my VPS (which has the i-MSCP installed), and yet, this overloaded .. it only remains free 7mb .... why? ... do not know!!, please help!

free- m

Code

total used free shared buffers cached
Mem: 1024 1019 4 0 0 0
-/+ buffers/cache: 1019 4
Swap: 0 0 0

Hello ;

You take us for gods? How do you think we can give you an explanation if you doesn't provide more information?

If you want get any help from our side, provide more information. In you last free -m, I see 1019 MiB available...

What is the result of the following command (when the free memory is less than 10 MiB) ?

Code

# ps aux | awk '{print $2, $4, $11}' | sort -k2r | head -n 10

BTW. running several services (HTTP, PHP, MAIL..) on a vps, which has only 1024 MiB RAM and no swap is a crazy thing...

Thanks.

in this link - http://wiki.i-mscp.net/doku.php?id=about:system, said ; minimum 512 RAM

note: transferred all my sites to my godaddy hosting and still is overloaded: (

note 2: for me Nuxwin you are a God!, xDDD!!!
