Do you have any idea that what was the action you did after that these errors got logged? Also did you recently moved your store? Are you getting these errors when accessing feeds?

No idea..I can get up to about 30 of these a day. Store has not been moved. Not sure if it is being caused by some file I modded or what. I was hoping someone could tell by the error where to look.

I get alot of invalid viewstate errors with the same resource.axd file in my event log, probably 8-10 a day.

Never have been able to narrow it down

Anyone want to help us get to the bottom of this?
