5  PROBLEMS ADDRESSED IN VAXSYSL01_073 KIT


      o  OpenVMS V7.3 nodes do not correctly handle Quorum Disks.   This
         can  result  in either CLUEXIT bugchecks or numerous connection
         manager console messages, such as:

            %CNXMAN, Proposing modification of quorum or quorum disk
            membership

         Any cluster with a quorum disk and  V7.3  nodes  requires  this
         fix.
