Illegal Sector Number to Cache.

Occurs on:  68 only.  This is an Abend error.

Meaning:  The Cache manager in the multi-tasking kernel attempted to
          read and cache a sector of disk that does not exist.  The
          sector number does not exist because it is higher than the
          number of logical sectors on that particular disk.  This error
          is the result of a failed internal consistency check and
          should never occur in NetWare.

Cause:  This error could be caused by a memory failure in the file
        server and could be attributable to either a hardware failure or
        poor power line conditioning.  A corrupt operating system file
        might also cause this error.

Solution:  Reboot the file server.  If this error or other Abend errors
           occur repeatedly, reinstall the operating system and then
           check the file server's memory and power line conditioning.
