    * Vps problem, my fault? their fault? bring light to this please

    Well for the last 2 months everything run fine with my current vps host, suddenly an email is sent about a Service problem with Iternap and all went down for a while then they restored it.

    The thing is that 15 days after that sucess im gettin this 100% cpu usage every day at almost all times, i tried them to solve this and they do fix it for a while but then again im back to slow land, so slow that makes pages unavailable for hours, i must add that i didnt add anything new to the server, the same old pages that runned fine for 2 months.

    Heres a pic of my control panel, since i dont want to bad mouth my hosters i uploaded it to a public site:


    *Change the * for t since it dont lets me post the picture.

    You can see there, this was taken a few minutes ago, Mexico time atm its 9 pm.
    So my cpu averages are low as always, it was way lower tought like 2-3% at this time usually but you can see 8 to 11% in the screenshot, but the thing that is wrong is the CPU usage there 99% to 100% almost at ALL times wich is causing countless critics from my visitors AND my clients.

    I sent several tickets to my hosters and they say that is the sql, then apache, etc, but the problem comes back few hours after they touch it. I also notice that tought they manage to bring the site speeds to "decent" levels for 1-2 hours, virtuozzo stays the same, so slow i cant use it, also told them but i didnt have a reply about this.

    Yes i tried several web browsers, still the same, so im starting to wonder and after 15 days of see my incomes suffering everyday a little more that maybe is not me and is them, that they oversold this server and im suffering the results?
    Can someone bring light to this since im not all that tech, but i do have a nice compilation of pics, invoices, logs, tickets logs, etc. about this issue in the case in one of "those" hosting providers.

    Hi, ok now after a few hours and sending them all the screenshots i have showing the cpu at 100% they replied telling me this:

    As per your notification we have monitored the server for cpu usage and load. But we find that at present the server load and cpu usages are just fine. Please do check and let us know the details for any further assistance.

    So i was like WTF, since that usage is not normal and i suppose they do have logs showing all that is happening at this server, this reply was sent after 3 hours i sent the screenshots, so i logued into virtuozzo, 4 am in the morning Mex time, 3.86% of my usage of bandwith and oh surprise the CPU was at 100% again, i have taken several screenshots more and sent them those and ill tell you what i get in response in a while, im starting to fell that this people is thinking im dumb or something.

    Arrow Update 2

    Hi, this next update as promised, well around 5:30 Am i got a response from the tech amanger of this host service, telling me this:

    Thank you for your patience on this. We are aware of the issues you are experiencing, which we are working very quickly to get this resolved.

    And offering as a compensation a discount on my next invoice (??), well i was happy to see someone admits theres something wrong, but a discount for this meh, anyways i replyed that i dont care about a discounts, i just want the few sites i have running properly. I got right after a couple more what i consider autommated repsonses:


    I am checking with this issue now


    Our senior team staff will update you soon.

    Blah blah, well its 11:20 AM and the site are running good at moments... then unavailable again, i lost all access to my control panel for the server, so no more happy 100% CPU usage screenshoting for me.

    Well ill keep you people updated, post your comments.And thanks WHT for providing this wonderfull space for us.

    What processes you are running on server? Its too important to know these informations. And maybe they didnt limit your CPU correctly OR they are overselling.

    All these things are releated to your problem.

    Hi Batu and thanks for the reply, ermm i dont run anything other than apache, mysql (lowest load i can get, file is no bigger than 7 MB, so that shouldnt be a problem, same database as when the server run fine), and email service for like 7-9 accounts. Thats all i run in my server, this should not be a problem, since i have important clients, i have hired there the most expensive plan for VPS, enught to run way bigger things.

    Still i get what you see, but before this strange sucess my cpu usage was never this high, so yeah maybe overselling, i just dont run things that can get me so high in the cpu usage, and if by any chance i was i think they would have told me instead of accepting that they have a "issue" as in my previous post.

    ermm i dont run anything,
    this part is really important.. Or I can tell you the main node server's CPU isnt limited correctly per VPS account. This is why you are getting affect by others..

    Batu, i really dont know about nodes or anything, that why im using a managed service, as i said, when i first sign in with them it was all fine, most cpu usage at top hours was always under 8% and at night around 2%.
    I did have a problem with them at first since i contracted a plan and they gave me the basic one, but that was solved, but yeah it was a pain to get what i paid for and sent several tickets, even now im not sur im getting what im paying, but again since i run just a few websites all i care about is that those websites run fine.
    Thanks for your reply, i hope other experienced users like you can put their toughs here, atm im still in the same situation, sites work fine for moments and then they go unavailable, as i said before i lost access to the server control panel since i sent them the screenshots.

    I got in the directadmin control panel and these are the process i run:

    directadmin, exim, httpd, mysqld, named, proftpd, sshd and vm-pop3d.

    its too bad to hear that you are in same situation.. And you dont need to thank because if someone knows something, he should share it

    By the way, sorry but I cant do something else without seeing and logging into your VPS. Thanks

    Please type "top -c" without quotes by logging into VPS via SSH with root privilages and post the output here. I want to check.

    Arrow Update 3

    Well after hours of suffering and waiting, the problem got finally solved, now my cpu usage is in the low again (less than 1% atm), all is running extra fine and i hope it stays there.
    The reason, no clue i didnt got any information on what caused this but im happy its solved and i dont have to move out, ill leave this topic here to anyone for reading and im not going to post further updates unless there are problems again wich i hope this is not the case.
    Thanks a lot to all that take the time to read and to Batu for his kind replys!

    Edit: One thing i noticed new is this value changed, wich i dont know if haves anything to do with this:

    cpuunits n/a n/a 1,000 pcs CPU share the virtual private server will get

    Notuce the 1,000 there, it was a 50 before the thing was fixed.

    Good gravy. 50 CPU units?!?!?! No wonder. Fropm now can keep a tab on allocations by typing this:

    cat proc/user_beancounters

    50 CPU units is plain highway robbery...I don't care if you're paying $5.00/month.

    A P4 2.8Ghz with 1GB RAM has 139129 CPU unites total.

    Heck..the VMware VPS I did testing on had 110179 CPU units total.
