This week, with no known changes to DHCP, network or CUCM, our 7937 phones are starting to check in with DHCP every 3 seconds. They have a valid address and work fine, they are just constantly hitting DHCP. Ideas are appreciated in advance.

I'm guessing it's this bug which is resolved in Firmware 1-4-5;
Thank you for your response, I managed to find the bug and have now upgraded the firmware, however out DHCP lease is set to four days.
Recently I've had 7941's and 7942 causing DHCP storms, a reset of the phone seems to stop the continues DHCP requests however this keeps happing. Any ideas welcome.
