UDP packet drop at TDI

NTDEV
1

Hi Folks,
I have a TDI driver that uses UDP for packet transmission and reception. I
am experiencing packet drops when we try to receive UDP packets sent in bulk
by the TDI layer. The strange part is I am able to see the packet at the
adapter level indicating the packet was not lost on the network. I am not
understanding why TDI or may be NDIS is not forwarding this packets up the
chain. Is there some way in which this behaviour can be changed or at least
explained.

Thanks in Advance.

Perhaps you are running out of buffers (i.e. they are not being freed fast enough). You should be able to interogate your NIC statistics for dropped packet counts.
