I can't remove a line from my config:

Router(config)#no ip nat inside source list 101 pool MY_POOL overload

Dynamic mapping in use, do you want to delete all entries? [no]: y

%Error: Dynamic mapping still in use, cannot remove

Router(config)#int g0/1.1

Router(config-subif)#no ip nat inside

Router(config-subif)#end

Router#clear ip nat translation *

Router#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#no ip nat inside source list 101 pool MY_POOL overload

Dynamic mapping in use, do you want to delete all entries? [no]: y

%Error: Dynamic mapping still in use, cannot remove

Router(config)#int g0/1.1

Router(config-subif)#ip nat inside

Router(config-subif)#end

I don't even have a access-list of 101 and I don't have a pool setup called MY_POOL:

Router#sh ip access-list 101

Router#sh run | i MY_POOL

ip nat inside source list 101 pool MY_POOL overload

Router#

How can I remove this thing? I'm stumped.
