    • system log rddcached errors

      Hello, i have OpenMediaVault installed on a raspberrypi.
      Release: 3.0.52
      Codename: Erasmus
      Linux raspberrypi 4.4.26-v7+ #915 SMP Thu Oct 20 17:08:44 BST 2016 armv7l GNU/Linux

      When i look into the syslog, it is full of messages with rddcached errors. I don't know what is causing them and can't understand on the internet what this rddcache does.

      I must not fear.
      Fear is the mind-killer.
      Fear is the little-death that brings total obliteration.
      I will face my fear.
      I will permit it to pass over me and through me.
      And when it has gone past I will turn the inner eye to see its path.
      Where the fear has gone there will be nothing.
      Only I will remain.
