ping -s not working

I have a multipath system with 2 physicals, a virtual and a failsafe. All network connectivity is working fine to and from all of the interfaces and the virtual. The one thing that is not working is 'ping -s'. From this machine, I cannot send and receive packets using ping -s. ping without the option works fine.

While the ping -s is running, I can snoop run snoop and see that the packets are leaving one interface and returning on another. Is there anyway to fix this so that ping -s works? See code below, atiems is the IP of the virtual interface:

bash-2.03#  ping -s 10.160.131.103
PING 10.160.131.103: 56 data bytes

Does it work if you specify the interface with -i?
