My server load and memory used keeps on increasing every second until my vps goes down.

im using wordpress and im not updating nor doing anything on my site. i just dont understand why my vps overloads.

i already restarted the vps couple of times and its no use

High I/O activity on the host Node can cause high load on all VPS in a virtualized environment. How much traffic are you getting at this time?
 
sorry i dont know but my site usually gets a 30-50 online visitors.

btw my vps has cooled down down after more than an hour of overloaded resources.
 
Well, it's not a lot, at all.

You should get in touch with hosting company and let them check I/O activity on the host node. It may be oversold or there may be an abuser.
 
my VPS is overloaded again. :(

site is down.

i think you are right about here, because i just restarted my vps so the system loads should also reset right? but i checked in whm its still overloaded and not being reset. and after couple of seconds it went so slow to being down.


Right before it went down again

Have you run top or mtop or phpsysinfo to actually see what your scripts are using ??

It probably is oversold but showing the host proof before being asked to be moved is always a good start.

this command i need to run in the commande line? i cannot access my root right now. i only have couple of seconds to check my server after i make a reboot then its down again

"95.5%wa"

I/O is tanked, this confirms what I said above. It is what you need to show the host and they should know what it is(well, hopefully).

@Krun!x "95.5%wa" what does it exactly means?

thanks again for the reply!

It is I/O wait. In simple words there is way too much writing/reading to/from drive(s) on the host node.

Possible solutions:
1) Add more drives to the array, or upgrade to faster drives, such as SAS or SSD.
2) Migrate some customers from this host node, as drives are clearly over-utilized.
3) Remove the abuser if that is the case.

It is hard to know without knowing numbers from host node and hardware specs of host node.
 
@tut2tut thanks! but i think if i do that my server will restart every second because its overloaded even before my site goes up. (i think)

@Krun!x ill be waiting for the reply of the support where im hosted. actually im only on my 2nd day on this hosting provider. and it went down twice, and now its down for almost 3 hours.

I apologize you are facing this issue, just to be clear to people who don't know which cloud technology we are using. Basically it's not possible for us to oversold the resources because we are using SingleHop private clouds which is developed and controlled by SingleHop and it uses KVM virtualization.

We can only create a new cloud server on SingleHop private clouds if we have that required amount of RAM and Hard Disk Space available on hypervisor. So I can assure you that cloud servers are not oversold and the reason for such a low pricing of cloud server is because we get some special deals from SingleHop.com

Some of our members with similar kind of websites are facing such issues because resources are just not enough to handle the traffic of their website or the process their application performs.

I will ask techs to install CloudLinux on your server and we might be able to avoid the crash.
 
See the output above. Drives are over-utilized(notice iowait if you aren't sure what to look for). Your best bet is getting SingleHop to take a look.
 
I will update your ticket with screen shot of why your server crashed. For other people who are trying to be "smart" it's not IO wait :)

He provided top outputs above. Don't you see iowait?

I'm not trying to be smart. I'm actually smart enough to read the top output. Have you read the Linux bible? You definitely should :)
