Symptoms

Consider the following scenario:

  • You have a Windows Embedded Compact 7 image for a multi-core processor device.

  • The image includes TCP/IP components.

  • You start the device.


In this scenario, you may experience a system crash.

Note If you check the stack trace, you find that the crash occurs in the TCP/IP start code.

Cause

This problem occurs because a race condition occurs in which the TCP/IP start code tries to access an object that is not initialized. This causes an access violation to occur.
