I have a Asp.Net webform that I placed on our production web servers. At first, the form worked great. Then, I started getting the below error message.

The error cleared it self up, but what exactly does it mean and how can I avoid this from happening again?

Also, this webform querys SQL Server tables to create a DataGrid menu.
