Hi,<div><br></div><div>I'm getting following error from Zenoss monitoring setup, but the root cause is unclear. </div><div>Possibly you could give some insight or tips where to look at? Already tried via Zenoss community forum (<a href="http://community.zenoss.org/thread/18663">http://community.zenoss.org/thread/18663</a>) but no luck there so far.</div>
