I am getting a lot of errors using the carpdev BETA patch against HEAD
provided by Max a few days ago. I don't know if I should be concerned
about them or if they are just informational. These are the main two
carp/vlan devices causing errors, but it happens on others as well -
at random times.
carp_iamatch(vlan2, xx.xxx.xx.37, xx.xx.xxx.137, ...)
not: carp2
carp_iamatch(vlan6, xx.xxx.xx.6, xx.xx.xxx.169, ...)
not: carp6

I also got this error when I had an IP on fxp0 and carp100 using carpdev fxp0:
arp: xx.xxx.xx.34 is on fxp0 but got reply from 00:03:47:71:a8:b3 on carp100
carp_iamatch(fxp0, xx.xxx.xx.37, xx.xxx.xx.34, ...)
arp: xx.xxx.xx.33 is on fxp0 but got reply from 00:0c:f1:bb:66:84 on carp100
Please advise, I am filling up message logs at the rate of every 3 hours!!
On a side note, this machine is serves vlan trunks which is why I
needed carpdev in the first place (as to not waste more usable public
ips with two gateway ips in a /29 that are silent just to run the one
gateway needed), thus giving my customers 2 useable IP addresses.
With carpdev I can give them 5. Currently, an OpenBSD 4.2-current box
serves as the "MASTER" and I am using a FreeBSD 8.0-CURRENT box to
serve as "BACKUP". When I rebooted the OpenBSD box, everything failed
over as it should, but I got more carp_iamatch errors on almost every
vlan/carp pair. Could the OpenBSD <-> FreeBSD differences in carp be
causing these errors??
Thanks for any assistance,
