An entity object cannot be referenced by multiple instances of IEntityChangeTracker

I am getting the following error while trying to update an entity, 'An entity object cannot be referenced by multiple instances of IEntityChangeTracker' The code runs as,

        dbUsers.Users.MergeOption = MergeOption.NoTracking;
        dbUsers.Users.Attach(user);
        dbUsers.ObjectStateManager.ChangeObjectState(user, System.Data.EntityState.Modified);
        dbUsers.SaveChanges();

Please help me to get rid of it.

If you use same Context*(dbUsers)* any where better to use context*(dbUsers)* as singleton instance.

This will Ensure a class has only one instance and provide a global point of access to it
