[Bug 782322] Re: plugin iostat_ios looses track of its state

[PresuntoRJ]

** Description changed:

  Binary package hint: munin
  
  Plugin iostat_ios regularly loses track of its state and no longer plots
  a graph. In munin-node.log the following lines are logged:
  
  [8468] Error output from iostat_ios:
  [8468]  Magic number checking on storable file failed at ../../lib/Storable.pm
  (autosplit into ../../lib/auto/Storable/_retrieve.al) line 380, at
  /etc/munin/plugins/iostat_ios line 218
  [8468] Service 'iostat_ios' exited with status 255/0.
  
  The only remedy I have found so far is deleting the state file
  (/var/lib/munin/plugin-state/iostat-ios.state) and then running the
  plugin manually to check (munin-run iostat_ios).
  
  Steps to Reproduce:
  1. Install munin and leave it running.
  
  Actual results:
  1. It collects the values for a while (usually a few days) and then, iostat_ios stops producing data for graphing.
  
  Expected results:
  1. iostat_ios should keep producing data for graphing.
