    The upstream disable gentle shutdown and disable threads<br>
    by default. The difficult point is disable thread in bind6,<br>
    and the fix is on dhcp.<br>
    <br>
    We enable threads and backport the patch from fedora.<br>
    <br>
    Disable gentle shutdown will introduce other issue (dhcpd<br>
    could not stopped by SIGTERM)<br>
    <br>
    The root cause is enable threads, if we disable it, everything is
    ok.<br>
    <br>
    I will try to find a nice way to report upstream.<br>
