I recognised the process is crashing when it gets the very first packet to ff02::2
here's the strace part: Process 13196 attached - interrupt to quit select(5, [4], NULL, NULL, NULL) = 1 (in [4]) recvmsg(4, {msg_name(28)={sa_family=AF_INET6, sin6_port=htons(0), inet_pton(AF_INET6, "fe80::21f:f3ff:fe41:3a7c", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=if_nametoindex("eth1")}, msg_iov(1)=[{"\205\0\37t\0\0\0\0\1\1\0\37\363A:|\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 4096}], msg_controllen=64, {cmsg_len=36, cmsg_level=SOL_IPV6, cmsg_type=, ...}, msg_flags=0}, 0) = 16 rt_sigprocmask(SIG_BLOCK, [ALRM], [], 8) = 0 --- SIGSEGV (Segmentation fault) @ 0 (0) --- Process 13196 detached I'm not really sure, if that is an Ubuntu or a radvd bug.
