I've built a really simple page that binds a GridView to a ObjectDataSource. The code works fine everywhere I run it except in a specific site in on IIS8. The same code files in a new site on the same server, using the same ApplicationPool, works fine. What could possibly cause an OutOfMemoryException on one site and not another? The problematic site is actually running AspDotNetStorefront, however, the page doesn't reference any AspDotNetStorefront code, so I can't imagine it would be their code.
Given the nature of the error (no breakpoints in the page even get it, it just goes straight to the error) I don't know how to effectivly debug this.
My page:
<%@ Page Language="VB" %><!DOCTYPE html PUBLIC "-//W""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html><head><title></title></head><body><form id="Form1" method="post" runat="server"><asp:GridView ID="gvHistory" runat="server" DataSourceID="dsHistory"></asp:GridView><asp:ObjectDataSource ID="dsHistory" runat="server" SelectMethod="GetHistoryRows"
TypeName="AspDotNetStorefrontAdmin.ROIImportHistory"></asp:ObjectDataSource></form></body></html>In my App_Code folder:
Imports System.Data
Namespace AspDotNetStorefrontAdmin
Public Class ROIImportHistory
Public Shared Function GetHistoryRows() As DataTable
Dim localDatatable As New DataTable
localDatatable.Columns.Add()
localDatatable.Columns.Add()
localDatatable.Columns.Add()
localDatatable.Rows.Add(New Object() {"Hi", "Hi2", "Hi3"})
Return localDatatable
End Function
End Class
End NamespaceThe exception:

Any suggests are very welcome. Thanks.
