System.Data.Linq.ChangeConflictException: 2 of X updates failed.
  at System.Data.Linq.ChangeProcessor.SubmitChanges(ConflictMode failureMode)
  at System.Data.Linq.DataContext.SubmitChanges(ConflictMode failureMode)
  at PROJECT.Controllers.HomeController.ClickProc(Int32 id, String code, String n)

This is what I get very often. This action is done thousands of times a day, and I get this exception about once every 5 seconds. From what I understand it happens when something changes in the database in the period between creating DataContext and updating it. Am I right?

How can I fix it?

Update

I just debugged the error and found the following:

Table name: dbo.Stats
current value: 9852039
original value: 9852038
database value: 9852039

The Stats table is updated constantly. So how can I still make LINQ save the changes. With "classical" SQL Server access through SqlDataCommand I never had problems like that.

Ran into an odd behavior today with a many to many mapping of one of my tables in LINQ to SQL. Many to many mappings aren’t transparent in LINQ to SQL and it maps the link table the same way the SQL schema has it when creating one. In other words LINQ to SQL isn’t smart about many to many mappings… >>> More
