There is a Wind River SPR 24397 that might be vaguely relevent to this: "A
networked target does not respond to ARP requests for proxy entries
created with arpAdd(host, eadr, ATF_PUBL)" which is fixed by the Tornado
2.0 Cumulative Patch 3 available from WindSurf.  However be sure to read
the Special Instructions to this patch as it states "The fix for SPR 24397
breaks the Proxy Arp Server" unless you follow the additional instructions
given.  If you're using shared memory backplane networking it's very
likely that you'll be relying on the Proxy Arp server, so you'll want to
visit the WRS FTP site, but it then looks like you don't get the patch for
this problem!  I don't understand it completely myself, and I haven't
installed T2CP3 for ASD as a result.
