Hi all,
I am having the issues explained below , I did not find any bug related to the below error messages , your help is appreciated.
Here is an example of what each switch logs when a server drops offline. Sample logs taken between 5:32am and 5:35am on Feb 20. This particular one was having problems all weekend. Switch #1 encountered over 2000 interface resets. The corresponding VPC port on Switch #2 only had 13 resets.

Hello Saleem.
This looks like a physical layer problem
2012 Feb 20 05:34:35 q91-sw01-5010 %ETHPORT-5-IF_DOWN_LINK_FAILURE: Interface Ethernet1/10 is down (Link failure)
can you check the sfp on both sides adn the cable. can you also make sure if the server drivers are up to date. Can you connect the server to another port on the nexus and see if the same issue happens.

Test using TDR.
Command:
1. test cable tdr interface
2. Wait for about 60 seconds (because it's a Nexus); and
3. sh cable tdr interface
4. Please post the result.

Link failure is most likely as it states a cable / SFP issue on the
remote side. (SFP failure on the local switch would tell you link not
connected or sfp not inserted).
