Cisco ASA 9.1(1) nat issue

Hello,

We have ASA 5520 and we have upgraded OS from 8.4 to 9.1.1.

We have two outside interfaces OUTSIDE1 and OUTSIDE2, and we have configured Twice Dynamic PATs for some sessions.

ASA is getting dynamic default route(eigrp) from Routers in this interfaces (OUTSIDE1 and OUTSIDE2)

OUTSIDE1 has better DF route. Twice NATs of OUTSIDE1 are upper then the same TWICE NATs of OUTSIDE2.

In 8.4 OS when OUTSIDE1 is going down, for example, via "shutdown" command, NAT rule which was translating into OUTSIDE inteface is moving to another NAT rule and is translated to OUTSIDE2.

After upgrade to 9.1.1 OS and shutting down of OUTSIDE, interface nat is tranlating into OUTSIDE and is not moving to OUTSIDE2, though this interface is in shutdown state.

Is there any workaround about this issue?
