I have a Centos 6.4 server that's being used as a Cassandra node in a production environment, it is still working and responding to queries etc, but the load average is rather "high" a.k.a. buggy? In any case, you have to see it for yourself:

incredibly high load average

Has anybody seen something like this before? Any clue on what's causing it?

Thanks in advance!

EDIT: Adding output of cat /proc/loadavg as requested:

[root@vdc-08 ~]# cat /proc/loadavg
2715599674950.05 1351413955738.05 471218463336.32 1/479 8382

    Lol, highest load avgs I ever seen. – Mike Purcell Feb 19 '15 at 0:06
  • O_o I blame java. – EEAA Feb 19 '15 at 0:06
  • @MikePurcell Indeed, although the server is still running and the numbers keep changing over time. I'm just waiting until somebody sheds some light on it before restarting the server. – Sergio Ayestarán Feb 19 '15 at 0:13
  • Provide the output of /proc/loadavg – Matthew Ife Feb 19 '15 at 0:13
  • @MatthewIfe Done Matthew, thanks for taking the time to see it – Sergio Ayestarán Feb 19 '15 at 0:15

Almost certainly a kernel bug.

This question /proc/loadavg shows incorrect huge values suggested updating the kernel on the host and rebooting but did not specify what the root cause is.

  • I'm not using cludlinux, this is a physical server running centos, but still the explanation is sound. – Sergio Ayestarán Feb 19 '15 at 0:30
  • Did it work? Updating the kernel (with subsequent reboot)? – Mike Purcell Feb 19 '15 at 1:09

this was working for me:

add "elevator=noop" in kernel boot config.

High Load Average with modest CPU Utilization and almost no IO

    "was working" ... does that mean it does not anymore? – Pierre.Vriens Aug 16 '17 at 16:47
