This looks like the answer from your primary server has been sent to
the Solaris box, but the program that originally sent out the query on
`solaris' has closed this socket (due to a timeout, perhaps), so the
answer will be thrown away now.

AFAIK, ping -v prints all ICMP messages, hence it's normal that you
see them even though they are unrelated to the ping itself.
