TFS 2013 Upgrade 3 Admin Console hangs

Hi,

I upgraded TFS 2013 to TFS 2013.3 and it worked ok for few days. Now when i try to access TFS Admin Console it hangs. When I try to access through TWA its d same problem.

I did a)Recycle App pool b)Restart the TFS site c)Reboot the server  yet I find the same error.

Can you please help me in the right direction to fix the issue.

I get in the event viewer as below:
