The second network card, is where we are getting the high 'Recv dropped'
activity.
Recv dropped: addr            1158497
These packets that can not be identified by the HP3000 are coming from a
Window server running some Tivoli enterprise software monitoring system.
Few users know the IP address or DNS entry that will allow them to connect
to the Fastlnk2 card.  Used by HP3000 system to send and receive FTP.
The 'Recv Dropped' activity also makes my NMLG files very difficult to
use.  >99% messages about failure to process these packets.

To catch everyone up:
:run nettool.net;info="status;tcp;tcp"

broadcasts/second on
the second.

Something looks terribly fishy with the second link.
