We use both NV/6000 4.1 and NV5.0a/NT. Our customer is very anxious to
get us to agree that NetView status polling may be unreliable, and that
interfaces may appear to be down when in fact, all that is happening is
that the TCP/IP protocol on the machine being polled is TOO BUSY to
answer the ICMP request!!!

Is this in any way possible on TCP/IP for NT or AIX?

If the machine is TOO BUSY to answer a ping, is it not also TOO BUSY to
answer request for resources (i.e. it is effectively down anyway)?

Is it possible that some WAN router between networks could be TOO BUSY
to handle an ICMP packet? Would it not just keep trying?

Any help from you network techies would be very useful!
