Multicast on channel-bonding

Hi all,

Our beowulf cluster has recently got channel bonded on the latest kernel 2.2.15. 
Everything seems okay except the IP multicasting. 
By "tcpdump -i bond0", I find the multicast packets do reach the related nodes.
But the application can not always receive the corresponding packets. Most of
packets are dropped. It happens when I connect a socket to a MC group, and 
then use send. When I use sendto and specify group/port, things work fine. 

Any comments are appreciated.

Thank you.
