Can you try the following:

ping -S 192.168.112.181 host
and then try pinging 192.168.112.181 from the host?

I'm wondering if it is the old "em fails to send gratuitous arp on alias
addition" problem, back again.

Also, run "tcpdump -vvvxXs0 -i em0 host 192.168.112.181" on the host in
question and try pinging it from a different host.  Do you see anything?
