i am trying Juno *without *DVR and there are around 500 sub nets in each
network node.
Network nodes have 500+ dnsmasq process which are configured to give
ipv6,ipv4 addresses out of this some fluctuates 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" for ipv6 for all the dnsmasq process that are in D state.
i don't understand why duplicate ipv6 issue is coming when there are vlan
tags to separate each sub net.For ipv4 duplicate IP issue is not coming for
same subnet.
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?
