dhcp pool exhausted + dhcp conflicts

we have a 3750 and use dhcp services on the switch.  every so often we run out of ip's even though we have  much less users than the size of the allocated dhcp pool.  I've noticed that the dhcp bind table is full but a ping-sweep only shows very few ip's being assinged and used.  It looks like the IP addresses are not being released from the table even though I have decreased the lease time to 8 hours.

could this be a bug?

Did you check for duplicate mac addresses in the binding table?

Hope this helps

Can you post the related DHCP configuration and also the show ip dhcp binding from the time IP address allocation failed (if you have that handy).
