[Spread-users] 4.2 IP Multicast issues

[Marcelo San-Martin]

Hi Jonathan,

I patched 4.2.0rc2 and it works perfectly with the IP Multicast domain.

Thanks a lot,
Marcelo

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
