Compliance HealthSet unhealthy

Hello,

Today at 8 AM our Exchange 2013 server compliance health set went into unhealthy state.  I would like help understanding what this means and what kind of negative impacts this could have on the email server.  I'm not sure where to go here but it looks like out of the HealthSet 'Compliance' everything is Healthy except for ELCDumpsterWarnin...

What does this mean and where should I look next?
