Hello, This is my first time posting here so be gentle.
It seems that random CARP interfaces on our systems will just die, stop replying to any requests OR only 1 request out of ~50 will make it through, slowly. tcpdump also shows no traffic reach the interface. Only when that 1 request makes it through, we will see traffic arrive to the system. We've tried everything we could think of to bring the carp interface back to life such as reboot, run sh /etc/netstart and even going as far as rebuilding the system server from scratch with maven and dropping the site55.tgz file in there but none of these things fix the issue. When we change the VHID to anything else and restart the interface, it fixes everything and the interface is smoking fast again. When we change the VHID back to what it originally was, we're dead in the water. Again, change it back to any random VHID and the issue goes away. So I have narrowed it down to VHID. Whenever we run into this problem I just tell people to change it to anything else. I know the CARP interface's MAC address is generated by the VHID so I am sort of leaning towards it be an ARP issue and possibly not an issue with the OBSD system. But I am hoping for some hints or ideas from you guys. Thanks in advance for any help! RZ
