Spanning tree port lockout will nail you pretty hard with CARP. Make sure your switch ports (if managed switches) are in port fast. Also, make sure that you haven't inadvertantly turned on port security and limited the port to a single MAC (each CARP VHID uses a MAC along with the physical interfaces MAC).
When this happens, I do not have two masters for any single carp ip, so that would seem to indicate they do see eachother at least somewhat. Also, these are not managed switches, and the sync interface is a cross-over cable between the two dedicated sync interfaces, no intermediate hardware involved.
I just double-checked and the VHID's are different for each carp ip and the advertisting freqs are 0's on router A and 100's on router B.
After thinking about what you said, I decided to go and double-check what was plugged in where, and I think I found the problem.
The WAN should be ok: both routers' wan interfaces are plugged into a 3Com SuperStack DS Hub 500 24 port 3c16611, and the only other thing plugged into this device is the cable for the packets to be sent out through ( it actually goes through another switch before getting to the "modem", but I don't see a problem there ).
The LAN side is where I think I discovered the problem. Router A is plugged into my main LAN switch, a D-Link DGS-1024D, however router B isn't plugged directly into that, but a secondary switch, a AOpen AOW-605M, which is then plugged into the D-Link. Your statement above of "port fast" leads me to believe that the interfaces need to be able to see eachother's packets in a more-timely-than-usual manner. I will move both LAN cables onto the same router and then report if the problem goes away. Since I have all unmanaged switches ( well, I actually have one managed on the LAN, but we've never cracked it open, and it wouldn't ever see any of the packets in question ), would it be advisable to give each carp interface a dedicated switch, or is it safe for example, to hook both LAN interfaces to the aforementioned D-Link, which is a 24-port gigabit unmanaged switch which all my servers are plugged into?
