  I have a Munin master that's contacting 5 nodes at the moment and I'm seeing one to two warnings like this in the munin-update.log.

  [WARNING] Call to accept timed out.  Remaining workers: xyz;abc
  

  in your plugin configuration file add

  timeout 120

  or on a per plugin basis in plugin-conf.d

  [plugin_name] timeout 120
