    Description

      To replicate: take a host down, cause hints to it, wait for HHOM to kick in

      The issue is line 201 of HHOM:
      startColumn = keyColumn.name(); // repeating the last as the first is fine since we just deleted it

      That comment is false. The column may not have been deleted, since the endpoint could still be down. This causes HHOM to go into an infinite loop trying to deliver hints to a down host.
