NDIS memory allocation failure

Hi,

I am writing a miniport network driver for Vista.
After many cycles of disable/enable the driver fails on allocation failure. I don’t think that there is a memory leak in my driver (used pooltag utility and internal tracking)
Is it possible that there is a fragmentation issue? How can I debug it to and check the heap status (free bytes, contiguous memeory, …)

Thanks,
Shai

The call that fails is NdisAllocateMemoryWithTag. I have also tried the “priority” version with the highest priority.
