Hi,
Does someone here know of any stability issue with Win CE 5.0 network
stack?
We developed a wireless driver on Win CE 5.0 & started an overnight
ping to the AP. Next day, it hanged with an exception -

PID:a609d4c2 TID:5b3ef32 Fatal Stack Error, NOT Terminating thread

We understand it's a kernel thread which is throwing the exception,
but no other clues.
The same ping works fine if run over Ethernet (KITL) interface.
There is no dynamic memory allocation in the driver. It allocates
memory pool only when loaded & reuses it for normal pkt transfers.
I have few queries -
1. As said above, any known issues with Win CE 5.0 network stack? I
mean anyone got similar experience .. & it turned out to be some quick
fix somewhere in Win CE rather than the 3rd-party driver?
2. Is there any way to dig deeper into the crash site .. using the
debug dump? How do we find out which thread it is .. out of some 50+
threads in device.exe? I saw some msgs talking abt thread handle/IDs ..
but wonder if it's going to help to dig deeper?
Would appreciate any enlightening replies ..

Regards,
Partha
