[Dnsmasq-discuss] dnsmasq process in S, D state causing high load average

I have around 500 dnsmasq process which are configured to give ipv6,ipv4
addresses out of this some fluctuate between D and S state while others are
in continuous S state.Probably because of too many processes in D state
with "rtnetlink_rcv" in wchan its showing very high load average.
functions in stack when in D state:
[<ffffffff816360a9>] rtnetlink_rcv+0x19/0x30
[<ffffffff81653e25>] netlink_unicast+0xd5/0x1b0
[<ffffffff8165420e>] netlink_sendmsg+0x30e/0x680
[<ffffffff8160e32b>] sock_sendmsg+0x8b/0xc0
[<ffffffff8160e871>] SYSC_sendto+0x121/0x1c0
[<ffffffff8160f25e>] SyS_sendto+0xe/0x10
[<ffffffff817342dd>] system_call_fastpath+0x1a/0x1f
[<ffffffffffffffff>] 0xffffffffffffffff
but in couple of seconds it changes to S state with this in stack,all idle
process have this in stack.
[<ffffffff811d20d9>] poll_schedule_timeout+0x49/0x70
[<ffffffff811d2ac6>] do_select+0x5b6/0x780
[<ffffffff811d2e5c>] core_sys_select+0x1cc/0x2e0
[<ffffffff811d301b>] SyS_select+0xab/0x100
[<ffffffff817342dd>] system_call_fastpath+0x1a/0x1f
[<ffffffffffffffff>] 0xffffffffffffffff
interface in which dnsmasq is listening has " tentative dadfailed" in "scope
global" error for ipv6 .
Not able to understand why dnsmasq that are connected to interfaces that
have "tentative dadfailed " continuously changes between S and D state
while others are idle.
attached is the strace while dnsmasq is in D state.
Any idea about this issue?
