Hi Muhammed,
There is a serious bug related to your symptoms on the NX-OS that you are running i.e 5.1(3). I cannot share the bug details here. This bug hits N7K if you running 5..1(1) - 5.1(3). Infact, I have advised my all the customers to upgrade to 5.1(5) if you are in the same train or go to 5.2/6.0. In the first chance you should not be running the 5.1(3) as far as my recommendation go.
There are two options for you.
1. If you have redundant sup engines, you can fail-over to the standby one and it should clear out the message temporarily.
2. Upgrade the NX-OS to atleast 5.1.(5) or 5.2/6.0 as mentioned.
HTH,
