Can you capture the DHCP packets while running dhclient?

tcpdump -i vio0 -s 1500 -vv port bootpc or bootps

There may be a problem with the server, but it may just be that the
server is sending more than dhclient's fairly low hard limit on what
it is willing to accept (the buffer is a bit smaller than some
use cases foreseen by RFC 3442), the packet capture will tell us more.
