Hi again, again, The problem seams to be even more general (so I put freebsd-net in copy).
When I ping carp interface, I lost some pings... ping data-test PING data-test.embl.fr (172.26.9.236) 56(84) bytes of data. 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=7 ttl=64 time=0.183 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=8 ttl=64 time=0.217 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=23 ttl=64 time=0.273 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=24 ttl=64 time=0.217 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=25 ttl=64 time=0.219 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=26 ttl=64 time=0.132 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=27 ttl=64 time=0.203 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=28 ttl=64 time=0.157 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=29 ttl=64 time=0.191 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=30 ttl=64 time=0.238 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=31 ttl=64 time=0.226 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=32 ttl=64 time=0.272 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=33 ttl=64 time=0.215 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=36 ttl=64 time=0.180 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=37 ttl=64 time=0.314 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=38 ttl=64 time=0.169 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=39 ttl=64 time=0.206 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=40 ttl=64 time=0.170 ms 64 bytes from data-test.embl.fr (172.26.9.236): icmp_req=41 ttl=64 time=0.158 ms ^C --- data-test.embl.fr ping statistics --- 41 packets transmitted, 19 received, 53% packet loss, time 40184ms rtt min/avg/max/mdev = 0.132/0.207/0.314/0.045 ms Is it a bug, or am I doing something wrong ? Here is my network configuration: defaultrouter="172.26.9.254" hostname="pc234.embl.fr" cloned_interfaces="lagg0 carp0" ifconfig_bge0="up" ifconfig_em0="up" ifconfig_em1="172.26.14.234/24" ifconfig_lagg0="laggproto failover laggport bge0 laggport em0" ipv4_addrs_lagg0="172.26.9.234/24" ifconfig_carp0="vhid 1 pass 497500fd0f6c3988d1f advskew 10 172.26.9.236/24" Tomorrow I'll try with a carp interface that is not over a network bonding to see if the problem comes from that.
