I have found the problem: multicast address. On the same network exists another 
c5 cluster with 239.192.55.1 multicast address, and this cluster use this 
239.192.55.75 . I have changed this last multicast address by this 
239.192.75.25, and I have changed network interface where this multicast works 
(eth0 to eth1) and problems are gone ...

Thanks.
