Re: Help ! NDISTest - 2c_PerformanceProfile Test crashes intermittently

Thanks a lot for your reply Thomas!
It was a great help in moving forward.
I tried to find more information about the NDISTEST errors and found
that ...

NdisPacketAllocateSend: NdtAllocatePacket failed
-- This debugger message means that the packet pool is exhausted, and
there are no NdisPacket structures available to set up for a NdisSend.
Usually, this means that there is a problem completing sends.

NdtPerfSendDataDpc: Aborting--no handles available
-- This debugger message is seen if there are no packets available
-- to send for an extended period of time (about 800 msec). It means
-- that sends are not being completed properly.

But even analyzing the code hasn't got me to a point where probably the
sends are not getting completed properly, still digging in.

Meanwhile, i have changed the NDIS_PACKET_POOL_SIZE from 160 to 200 and
the crash seems to have gone. But live debugging still shows the above
mentioned errors. So to summarise, increasing the pool size is not the
solution.
But do you know if there is anything like an optimum pool size for NDIS
Packets ? Why only 200 has stopped the crash.
Infact the 1000's of pending packets which stopped the PerformanceBlast
test have also ceased coming.

Thanks again for your help.
I am trying to figure out where i might be going wrong.Will keep you
guys updated.
Waiting for any inputs regarding the POOL SIZE ?
