LINQ to SQL exception: System.OutOfMemoryException

Question

Not sure why I keep getting OutOfMemory exception. I am using ASP.NET MVC with LINQ to SQL. Here are some of the stack traces:

Answer 1

What is your expression? The problem seems to follow from this line:

 System.Reflection.Emit.DynamicMethod.CreateDelegate(Type delegateType) +7652553 

This bias seems rather strange. I can hardly believe that the usual dynamic method will have a body of 7.5 MB.
