Well, let's see...

- no logs
- no configuration
- no lease database

Nope, no one can tell you why.

Try asking again with relevant log entries, a _complete_ copy of your 
dhcpd.conf (not just the parts you think are important), and some idea of 
what leases have been given out (I hesitate to suggest posting the entire 
dhcpd.leases file only because it may be quite large and mostly 
irrelevant).  Then someone may be able to help you figure out the problem.
