Re: [lvs-users] ip_vs_send_async error

Hello!

Finally we have place our LVS in production. We doesn't find any errors in
test scheme. But there is problem in production environment. We are using
connection sync and every second above 100 error messages comes to
/var/log/messages on LVS Master server.

Dec 14 12:06:42 lvs-master kernel: IPVS: ip_vs_send_async error
Dec 14 12:06:42 lvs-master kernel: IPVS: ip_vs_send_async error
Dec 14 12:06:42 lvs-master kernel: IPVS: ip_vs_send_async error
Dec 14 12:06:42 lvs-master kernel: IPVS: ip_vs_send_async error

I try to start connection sync daemon different ways:

1)
/sbin/ipvsadm --start-daemon=master --mcast-interface=eth0 --syncid=1
/sbin/ipvsadm --start-daemon=backup --mcast-interface=eth0 --syncid=1

2)
/sbin/ipvsadm --start-daemon=master
/sbin/ipvsadm --start-daemon=backup

3)
/sbin/ipvsadm --start-daemon=master --mcast-interface=eth1
/sbin/ipvsadm --start-daemon=backup --mcast-interface=eth1

But every time get the same errors. I can see connections from lvs master on
lvs backup so connection sync is work.

My kernel version is 2.6.31.2.
My ipvsadm version is ipvsadm-1.24.


Regards, Aleksey
