SYMPTOMS

Consider the following scenario:
  • You have a Windows Embedded CE 6.0 R3-based device that uses NAND flash memory.
  • The flash memory uses the model device driver (MDD) and the platform-dependent driver (PDD) flash driver models.
  • You try to mount and then unmount the NAND file system.
In this scenario, a memory leak that is about 4 kilobytes per cycle occurs.

When this issue occurs for a long time, the device may have to be reset to recover from the issue.

Note If you use the Application Verification tool, you notice that the leak occurs in the Flashmdd.dll module.
