Well, you could file a bug report, but I'm not aware of this error happening on other platforms, so it might end up being a kernel issue of some sort.

Hi Kevin,
Thanks a lot. Please find the more details for the same. BIND version : 9.3.6 OS version : HP-UX 11.23 I have look at the *socket.c* file and seen that "

This error indicates that sendmsg(2) failed with EDESTADDREG ".

----------------------------------------------------------------------------------------------------------

     cc = sendmsg(sock->fd, &msghdr, 0);
              send_errno = errno;

isc_sockaddr_format(&dev->address, addrbuf, sizeof(addrbuf));\
                        isc__strerror(send_errno, strbuf, sizeof(strbuf));

                        dev->result = isc__errno2result(send_errno);\
                        return (DOIO_HARD);

Note : This same is also seen on BIND-9.4.3-P3

    "#53" designates *port* 53. Nothing unusual about that.

    To me, this looks more like a kernel issue-- EDESTADDRREQ is what
    you get if you try to send data via a UDP socket that's not
    connect()ed. BIND keeps good track of what's connect()ed and what
    isn't; it's like the kernel is losing the association somehow.

    Without knowing what OS this is running on, or what version of
    BIND, it's kind of hard to troubleshoot further than that.

           sounds like a routing or firewall issue. Although from the
        limited
           post " #53 " doesn't look right.
