In Dynamics AX 4.0 or Dynamics AX 2009 it can happen that a lengthy operation terminates with the following error message in the InfoLog:
Error executing code: Insufficient memory to run script.
A typical example that can result in this error message is when you are running the Reverse Engineering Tool of Dynamics AX 4.0 SP1. Another very common situation is when you are trying to process very large AIF messages with several thousand lines within AX or within an application that uses the Business Connector like the AX BizTalk Adapter.
With Dynamics AX 4.0 a new mechanism was introduced to limit the maximum amount of memory that can be allocated by variables (in X++ code) in a session. This maximum amount is set to 10 MB by default. For some operations like large AIF messages (that are stored in memory during processing) this is however not enough and so the operation is terminated when the maximum amount is reached.
