It seems UCX intentionally prevents listening on ipv6 loopback? https://github.com/openucx/ucx/blob/v1.12.x/src/ucs/sys/sock.c#L134-L140 ``` if (ifa->ifa_addr->sa_family == AF_INET6) { saddr6 = (const struct sockaddr_in6*)ifa->ifa_addr; if (IN6_IS_ADDR_LOOPBACK(&saddr6->sin6_addr) || IN6_IS_ADDR_LINKLOCAL(&saddr6->sin6_addr)) { continue; } } ``` Removing this and setting `UCX_TCP_AF_PRIO=inet6` fixes the issue. -- This is an automated message from the Apache Git Service.
