[Spread-users] 4.2 IP Multicast issues

[Jonathan Stanton]

Hello Marcelo,

I've isolated what was going wrong with the multicast joins in this case, it was a change in behavior of the underlying multicast code we use. Please try the attached patch which applies to the 4.2.0rc2 release. It should fix the problem. 

I'll also release a new version in the next day. 

Thanks,

Jonathan
