we  coded web application using nettiers for data access.  and we found a such an exception in nettiers v2.2.0603.

It is said that this problem has been solved in version v2.2.0603. But i still find this problem and it happens randomly. It seems to be caused by  Multithreading.

Inner Exception: System.IndexOutOfRangeException: Index was outside the bounds of the array.
