I also saw something similar today on AIX 4.3.2, I tried to ping from the
commandline, at the time AIX snmp agent was being hammered by a request
from another machine, and I was ftping a file to another machine. Still
trying to see if I can recreate and fine a cause.

Just curious - AIX 4.3.2? We had a similar problem a while back. The
problem
just "went away" - I am still puzzled over it. We could not ping a certain
web server from NetView but could ping the server from other hosts. Now to
add to my confusion - all the while that pings were failing I could do SNMP
gets and HTTP requests just fine - only pings were failing. I might add
that
two different ping programs were tried (the AIX supplied one and the public
utility called "fping") - both failed. It was not an arp cache problem. As
mysteriously as the problem appeared it just went away.
