  I gdb'd the process and it seems to be running like heck in radck().  
I guess it's trying to rebuild the file into a dbm format?

  Nothing is connecting to the radiusd during this read to make it do 
an IP lookup, but I did an nslookup and it seemed OK.  I tried using 
'-n' and no change there, either.

   Right.  However, that doesn't mean that it's ready to receive 
requests.  Do a 'top' after you do the hup.  See what the radiusd 
process is doing.  It's eating the CPU.

  Further investigation reveals that the builddbm process is calling 
the radiusd to build the db.  It's calling the same functions that are 
being run while the main daemon is spinning.  The weird part is that it 
takes about the same 2 minutes to generate the db file.  This is *way* 
*way* *way* too long.  makedbm can generate the file in about 8 
seconds.  Also, the resulting db from GR is 21, yes *21* times the size 
of the users file.  That can't be good at all.

  I tried using 'radiusd -b' to make it use the db, but it doesn't seem 
to want to.  Any ideas about that?
