Warning after upgrade and restart Arcadia Visualization Server on Ambari

After upgrading Arcadia in a Hortonworks environment its possible you might see a warning like this:

41%20PM%20copy

This warning should be ignored in most cases, and is related to a race condition between the Ambari status checks and the start of the Webserver component (running on port 35000) of the Arcengine daemon that the Arcadia Visualization Server is connected to.
