That set of lines is incomplete.  There should be more from dbclean
including its announcement of its version number.  For example, this
is what I see in a quick test:

    Jan  5 16:49:26 calcite dccd grey[14294]: lock open(/usr/home/vjs/dcc/working/grey_db): No such file or directory
    Jan  5 16:49:26 calcite dccd grey[14295]: database initially broken; starting `/var/dcc/libexec/dbclean  -Gon -i 101 -Gon -h. -a ,6999 -4`

    Jan  5 16:49:26 calcite dccd grey[14294]: 2.3.25 listening to port 6999 with /usr/home/vjs/dcc/working and 10 MByte window

Ignoring the missing long entries, your log seems to say that:
  - `dccd -Gon` started and failed to find the greylist database
  - so dccd started dbclean
  - dbclean wrote the magic string into the new /var/dcc/grey_db-new
     and then failed to find it.

I have some theories:

   - /var/dcc/grey_db-new already exists and is corrupt.  /var/dcc is
       probably not writable.

   -  your UNIX-like system has a crazy filesystem that does not play
         nice mmap() games

   - you have an "improved" version of the DCC source from a third party.
