Cause

• This notification/error above is normal, as the startup command is polling the Solr service to confirm if it's online.

Resolution

• Nothing to be done.  This message isn't harmful and does not allude to an issue.  In previous EDR versions this message was happening, but hidden.  An Engineering Request has been submitted to hide this message in an upcoming EDR build.
