Hi Marce,
The bug documentation seems to affect only ASR and doesn´t has a fixed release.
I will apply the command ip nat settings nonpatdrop, it seems to be final solution but I dónt know if the output of show ip nat translations filter entry-type half all is enought evidence.
#show ip nat translations filter entry-type half all

I will keep updated if it works.

Hi Gerardo,
Did the nonpatdrop setting fix your issue?
I'm having the same issue on my ISR running 15.5(3)S4b.
Thanks,
Richard

Hi,
ip nat settings nonpatdrop and clear ip nat translations * stoped the logg.
