Teaming configuration and multicast

I have recently had an issue with multicast on 2 HP DL380 G4's and would like some advice.

The servers were originally configured with both nics teamed and setup for transmit load balancing with fault tolerance. However, when using a java utility to test multicast neither server responded to the other.

Our networks team ran a trace and we could see that the multicast traffic was going out on the primary interface and responses were being received on the secondary interface. I have got round this by configuring both servers to use Network Fault Tolerance only.

Obviously by doing this we have lost half the available bandwidth which shouldn't be an issue but I'd like to find out whether multicast should work when using multiple adapters configured for transmit load balancing or not?

Any help would be much appreciated.
