I found that but I do not have any helper-address in my config

%IP-3-LOOPPAK: Looping packet  detected and dropped

The %IP-3-LOOPPAK: Looping packet  detected and dropped error message is received because of a looping  packet that has been detected. A common cause is a misconfiguration of an IP helper address. The helper address  should be the same address as that of the server of the intended service.  Putting the address of the router in the helper address causes a routing loop to  be created.

The recommended action is to  analyze the source and destination address of the looped packets and verify that  the configuration of the IP helper addresses in the router correctly points to  the right device and does not point to the local router  itself.

can anyone help me?

Thanks

I would start updating to 15.0(1)M4 that is known to be more stable.

Did you ever get an answer to this question.  I am seeing the same messages in my logs now.
