Hello, I have a setup with 2 openBSD boxes used as firewall, redundancy is made using CARP. Each has 4 NIC : 1 for internet, 1 for pfsync, and the two last are used as a trunk, collecting all other VLANs. Master's advskew is 10, slave's is 50. All worked like a charm since nearly 2 years, but since 3 weeks I have odd problems : * on the net interface, the backup becomes master, but the master remains master -> Nearly half of the packets are lost I did a tcpdump on the slave's interface, carp packets from the master arrive. But it remains master !

* on my DMZ interface (vlan 4), the carp is in INIT state. By the way, as it is part of a trunk, physical connections are good : they work for all other VLANs. When I shut down the corresponding carp interface on the slave (ifconfig carp4 down), master becomes master again. Could you give me any clue to keep my master in master state ?
