What is with the \xa0 characters instead of blanks (\x20) before the
zeros in that line?  Does the tool used to capture the log entry
convert some blanks to blanks-with-parity?  Is there something screwy
with the printf() library on the target platform?  I don't think it's
a bug in the DCC source, but am I wrong?

`dbclean -SN` would have emptied the database.
As checksums flooded in, the hash table for the database would have filled.  
Normally, a timer checks to see if the hash table is nearly full and starts
`dbclean` to rebuild database with a bigger hash table.  Evidently in
this case by the timer fired, the hash table was too full and there was not
enough room to add the checksum for the server-ID claim.  As a result,
`dbclean` was run in an emergency repair mode.
