Environment contains an OS X 10.6.8 Server with OS X 10.8.2 clients. DHCP is running on server with a lease time of 1 Day (86400 seconds). The system log is flooded with DHCP REQUEST/ACH messages logged every 2 hours (not the expected 1 day interval). See log "Server Log" below.
On the client side. I checked the contents of var/db/dhcpclient/leases for the en0 interface. This is the only interface enabled. The results are as expected. The LeaseLength key has a value of 85536 seconds (assuming it will decrement from the LeaseStartDate). See file "var/dv/dhcpclient/leases" below.
Any insight as to what might be causing this behavior would be greatly appreciated. Thank you!
