    Question 16-40+ Load, Yet 90% of CPU is idle (and) 0.00 IO waits. What could it be?...

    Hello,

    I have a really challanging task of knowing why and host to fix the situation
    where at most times the CPU is totally idle and same for IO activity, yet the
    load at most times is 16-40+.

    For instance at time of writing this: The load is 16 now and linux says:

    avg-cpu: %user %nice %sys %iowait %idle
    0.49 0.40 0.90 0.00 98.20

    (That's a whopping 98.20 idle state!)


    How could that possibly be? And could you wonderful folks attempt to offer
    me advice on how to find out why load is so high yet almost totally idle activity.

    If you need various commands for me to run, let me know.

    If there's also any ADMINS (with good status) that are willing to look at this and
    think they can figure out this case, let me know. I'll gladly pay.

    Thanks.
    Andre

    Can you run top command . The top program provides a dynamic real-time view of a running system. It can display system summary information as well as a list oftasks currently being managed by the Linux kernel. The types of system summary information shown and the types, order and size of information displayed for tasks are all user configurable and that configuration can be made persistent across restarts.

    command to run :- top -c

    I f you want to sort the results by memory press [shift+m]

    To sort it by cpu usage press [shift+p] .
    To sort it by time press [shift+t]

    If you want me to look at it, send me a pm.

    Is the server performance suffering with this "high" load?

    If its performing fine, whats the problem...

    The thing is obviously when server has this high load, it's really slow.

    Here's: # top -c

    From the top results, i see apache is consuming cpu,

    Can you try restarting apache.

    Can you also post the result of 'ps ax'

    Yes when I restart apache, load gradually goes down. Then when I start it, load stays stable at about 8 (which is very fast actually), but then once again slowly averages at 16-40.

    Here's: ps ax

    What's strange in your top and what someone else was pointing out I believe, is that if you add up the CPU%ages from the top picture, the first 4 apache entries are using up about 50% of the cpu (18.2, 14.6, 10.9, 5.5). Yet the overall Cpu(s) line is showing 98.1% idle... that doesn't make much sense.

    Is this a multiprocessor machine, or single processor? If it's multiprocessor, hit I on the top, so you can see processor utilization broken out per cpu as well.

    Are you running the ps and top commands as root or as a regular user?

    I'm ofcourse running commands as root user as this is on one of my cluster servers.

    This server has 2 CPU's. Each one has 1x 1.86Ghz processor.

    Yes. As you have mentioned "doesn't make much sense", you're right. It doesn't.

    I'm used to usually figuring out via benchmarking. But this case can't be benchmarked (at least to my knowledge). The issue is just simply there.

    Eitherway, it can or others reading this attempt to give me some pointers, that'll be great.

    Perhaps there's a script that will tell more info about servers operations that I'm not aware of.

    Could you please show what does:
    Code:
    free
    show you?

    How much RAM do you have?

    Are your HDDs IDE or SATA/SCSI?
