Problem that is resolved in kernel rollup 978110
A memory leak occurs when you run the master scheduling process
When you run the master scheduling process in Microsoft Dynamics AX 4.0, the Microsoft Dynamics AX Application Object Server services may consume lots of memory. Additionally, the memory is not released even though you exit the Microsoft Dynamics AX 4.0 client. This problem occurs if static containers are used in an object that is called from another class.
