All,

One server of mine running CentOS 6.3. The load is very high, but few process in running or blocked. Followed is the output of /proc/stat, /proc/loadavg and top

  • And what??
    You are not giving any relevatn information about what machine what are the wanted results nor what this server purpose is.. It will be considered pretty OK for some services to be like that.

  • This issue happened again, who can help on this? system load up to 72, but /proc/stat only show that 2 processes were running and no process blocked. could it be a bug?

    The load depends on what the running jobs are *doing*. I *frequently* see loads of 70 and some over 100, on servers with 48 or 64 cores… but we do
    *really* serious number crunching around here.

    As others have already said, you are not giving and you are not looking at relevant information. You want to look in top at the running processes, for instance. It doesn’t matter at all that you have “only 2” processes running. As it seems you don’t even know which were running. Find out!

    Btw, quoting old and new information adds confusion.

    The number of sleeping *2534* processes seems a bit high for me. What the hell have you running there in the background on a “tiny” 4 GB machine with “only” two CPUs/cores? You can either have a few (or just one)
    processes needing a lot of ressources or many processes waking up, each one just needing a little bit, but in total they count …
