High CPU load on rrdcached

    • OMV 1.0
    • Resolved
    • I've just started experiencing this from 9am this morning. Machine was up for 2 months no problem. I have raid10 with 4x 2TB Seagate Constellation ES3 disks. Top command shows CPU at 195% on rrdcached. I'm using a Intel I5 processor with 8GB ram. I thought it was an overkill using this config but it seems it's not enough. OMV version is 2.1.9.
    • I just discovered this same issue on my config

      2275 root 20 0 267m 2044 856 S 99.5 0.0 27358:30 rrdcached

      version 2.2.14

      Was this ever solved good or people just kill the process, i see notes that it came back for some members after a while, but i do not read any permanent solution?

      Does anybody have a clue about this?
      Could be this bug:
      github.com/collectd/collectd/issues/1948
      Meanwile, I killed the process.
      The effect is, that the graph about CPU load etc. are not updated anymore, a pity but better then 100% CPU load.
      Could I uninstall this tool completely?
