Load at exactly 1.00 when idle

As thread title. Anyone have an idea why that'd be? When the server is relatively idle, it sits at 1.00 as a baseline.

FWIW, it's an OVH 64G E5-1630v3

    I do. I'm not using it either, so I'll kill it and see if that does anything.

    Still @1.00 after MySQL stopping. I see the thread mentions full disks (which I don't have), but I did hack together the partition setup and that is perhaps related. I installed Ubuntu 14.04 on there using 1 of 3x300GB SSDs and set up partitioning/mounting and all that malarky myself for the other 2 disks, as I wanted the disk space of all 3.

    Perhaps the only other thing relevant is I'm running nginx on there, and a number of proxy_pass setups. top doesn't show anything being active. Installation doesn't have much else, it's a bunch of custom written apps that have data sitting in memory that serve requests via nginx to the outside world.

    My hunch is it's disk related, but thought I'd post here since a lot of folks have more hardware/OS experience.

  • RAID is syncing/checking? check cat /proc/mdstat

    Doesn't seem to say anything

    cat /proc/mdstat
    Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [multipath] [faulty] 
    unused devices: <none>
    

    Just in case this is relevant

    cat /etc/fstab
    # <file system> <mount point>   <type>  <options>   <dump>  <pass>
    /dev/sda1   /   ext4    errors=remount-ro,relatime,discard  0   1

    I'll dig further into that, thanks for the insights

  • Poll your /proc/interrupts using ITop.

    Did you try restarting the server (if you can), and does this problem persist?
