I've made some progress about (a). It's tricky. This caused by this fragment: if (vhost_user_read(vhost->sockfd, &msg, len, fds, fd_num) < 0) return 0; Here you ignore errors. And this particular request for some reason ends up in EBADF. The most magic part is that sometimes it just works... Not sure if i can finish it today, and here in Russia we have New Year holidays until 11th. Kind regards, Pavel Fedin Expert Engineer Samsung Electronics Research center Russia
