I don't understand the following error message

Hi

The last month I have recieved some error messages from one of my applications. I have set up global.asax to email me when unhandled exceptions is thrown. I haven't updated this particular application but the error messages has shown up for the last month. I don't understand them. Perhaps somone here understand? When the error occour the applications sends about 10 emails with small diffrences in them but all within the same minute. Then after a week or so... it happens again.

Does anyone have any idea about what could be wrong?

One of the error emails:

I have gotten these errors every now and again as well. They seem to be random and infrequent. I'm confident that they're a .NET 2.0 Beta 2 framework related issue that will be fixed when .net 2.0 comes out of beta. I wouldn't worry too much about them and just handle them by giving the client a new session and resetting their viewstate.
