I can confirm Scott's words - I was one of the people with the problem. My results where exactly the same as you are seeing (except mine was only on one interface). Carp multicasts stuff on the interface at regualr intervals and expects to see multicasts from the other system coming in. It is the frequency of these multicasts that determines who is master, and who slave.
The advskew 100 simply slows down the multicast rate of the slave. The fact that both systems are master means that they are not seeing each others multicasts. In my case the problem was caused by having a switch that was divided into different VLANs (by port). The two systems where plugged into the same switch, but not into the same VLAN. Once I had discovered this (by plugging them into the correct ports) the problem was fixed instanltly.
