Need help diagnosing a System Event "NullReferenceException" from ScrumForTeamSystem.EventService.Services.CachingService

Sep 19, 2012 at 6:27 PM

Browsing the System Event log on my TFS 2010 AT server I find a number of events recorded as below.

Has anyone else seen anything like this?  Could anyone give me a tip on how to diagnose where this might be coming from?
