[c-nsp] Port-channel strange issue ?

Hi
I've a port-channel (no LACP) config in this way on my 6509:

*******************************************************************************
interface Port-channel11
 description  Te1/8,2/8
 switchport
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1-3996,3999-4094
 switchport mode trunk
 logging event link-status
 logging event trunk-status
 load-interval 30
end
*******************************************************************************

I see the "Age of the port in the current state" of the second ten-giga link that seems up by few minutes...

The problem is that it doesn't refresh that timer...
If I repeat the command after seconds, minutes, or days it remains the same, the only counter incrementing is for the bundle...

Any idea why ? 
could it be a problem ?
I sometimes experience L2 issues...

On the opposite site of the port-channel the counter is about hundreds of days...

Tks
