Certain networking packets cause memory leaks in Windows Embedded Compact 7 on i.MX53

I have been tracking an elusive bug that causes the system to become unresponsive.

 

It has been proved that the bug is in the Ethernet area of the i.MX53 WinCE7 BSP which happens in certain network environments, especially in the European markets.

 

The system is leaking memory while processing certain Ethernet packets. The OS image has been built using the latest QFEs available as of 09/12/2019, i.e. WEC7 QFEs June 2019.

 

By disabling networking on the device, the memory leak stops.

 

This is a production system.

Please provide insight as to how to attack this problem.

 

Thanks,

Eugen
