new server with zero traffic showing high load

Discussion in 'Site & Server Administration' started by classifieds, Nov 30, 2005.

  1. #1
    I leased a new server a few weeks ago and finally got around to moving some applicatons over yesterday and noticed that the server load via "top" was unusually high given that there was nothing running on it.

    What's a typical load for an idle server? The host says that this is normal. I'm concerned that there's a confirguration problem.

    The server is a AMD Athlon64 3200 with 1gb of ram and an 80gb sata drive. It's running redhat with whm/cpanel .

    Should I be concerned? Are the specific questions I should ask?

    Well it depends. Would help to see more of the top output for example to see what is running. Is it being used as an email/db server? etc.

    Like jbw said, we need more of the 'top' output - maybe there's something wrong happened about zombie process.

    Show us what's generating it. View by CPU, and then memory and show what's say the Top 10 for each.

    Thanks!

    Here's the rest of the "top" display.

    Nintendo, How do I view by CPU and then mem?

    Doesn't look normal to me, it must be doing something that doesn't show up in the process list, you could try and paste the output of "ps auxw" or a reboot and see if it goes away.

    Whatever it is doing it isn't showing up as a process so I'm guessing it's filesystem io.

    Get the sysstat package if you don't already have it and run iostat. Look at the %iowait% value, at idle it shouldn't be many percent.

    Possible it could be related to the buildapache.sea that is running, seems that is some apache upgrade thing from cpanel?

    I think it may be the hosting company trying to solve the problem via configuration modifications (but I'm not sure and won't know until after 8:00am EST ).

    Ok,

    Just for comparison this is my iostat output from my celeron 2.4GHz, running apache and spamd:

    %user %nice %sys %iowait %idle
    4.38 0.00 0.65 0.00 94.97

    Shift+M for memory.

    That looks like CPU. If it isn't, Shift+P.

    Could well be that the storage for your server is on a busy NFS server. Load is calculated by number of processes waiting in the queue - if disk access is slow then it will show a high value.

    I've also seen this happen before with the crappy Dell 'raid monitoring' tools they used to ship - I couldn't see these listed in your ps output though, so I don't think this is the cause on this occasion.

    I gave up, canceled order and got a machine from different hosting company.

    I couldn't justify the time it was taking to determine the problem and I was too concerned about putting a high traffic site on a machine that had problems when it was idling.

    Thanks to all for the suggestions and input :)

    It is something waiting on IO, since the cpu is 99% free. Could be fine actually. Depends on what the processes is doing. This does not happent to be a Centos 4.2 box with cpanel does it?

    I had this same problem on a server earlier today. It turned out to be the Dell RAID array which was still building. Once it finished building the load returned to zero :)

    Like Shoemoney says, there was probably never anything wrong with it.

    Analog is using up a lot of memory. It's probably because you moved over your previous log files too and it's now processing them.

    Do a
    ps aux | grep analog

    and see if analog is still running. Could be a problem with analog configuration.

    I disagree. I have had a lot of dedicated servers and the new ones had very low load levels as expected. I have a dual 2.4 GHZ machine with 2gb of ram that has loads in the range shown in the original post - and that server has 50 client sites on it.

    I don't know what the problem was but the load on the new dedicated machine is fine.

    The other one may have resolved itself (or not been an issue) had I been patient - but time is money :)
