Sounds like a bug to me. If you post your "show ver" here I will look on the bug toolkit.

Hilton,
This kind of jumps out at me
CSCdy26008 -Failure to remove negotiated IP address
Symptoms: The negotiated IP address is not cleared from an asynchronous
interface when a call ends, even though the IP address is returned properly to
the IP peer pool.
Conditions: This symptom is observed when the peer is configured to dial in to
the network access server (NAS) and to obtain an IP address through IP Control
Protocol (IPCP) negotiations with the NAS. The NAS is configured with pools of
IP addresses to be allocated to the peer when the peers generate a PPP call to
the NAS. The NAS is also configured to authenticate the peer through RADIUS.
Workaround: There is no workaround.
------------------------------------
A lot of older 12.2 / 12.3 images are affected by this, though your IOS version isn't listed, that doesn't mean it is excluded.
I would suggest upgrading to one of the newest 12.4 releases and seeing if that clears your issue up.
-Gabriel
