Since things are working and 131K is more than 80K, you must have added
them to your servers's whitelists to be incorporated into your servers's
databases by dbclean.
Since you're already using server white-lists for IP addresses,
it seems reasonable to use them for other purposes.
Of course, unlike DCC client white lists where changes are noticed 
a few minutes after they're made, server white lists are updated only
when you run dbclean.

(Never mind that I'd probably use one sendmail access DB entry to
white-list each class-B network instead of 64K DCC server entries.)

I doubt I understand.  Server white list entries can be "ok", "ok2", or
"many".  "Many" is a blacklisting.  A message must have two checksums with
"ok2" to be considered white-listed.

I wish 400 file descriptors for 70 dccm threads did not sound like 
a file descriptor leak.
As far as I know, other systems including one on "SunOS 5.8", are not
having similar problems.
