  STOP 0x00000041 MUST_SUCCEED_POOL_EMPTY (0x1000,0x440,0x2E,0x1)

  Parameter 1: The size of the request that could not be satisfied (0x1000)

CAUSE
=====

This message is caused when high numbers of UDP packets are received by the
server. The receive queue of the server eventually gets backed up and it
eventually runs out of memory when allocating memory descriptor lists (MDLs) for
the data coming in.
