CARP not failing over all interfaces

[PacketMaster]

Hi All,

unfortunatelly i have a probelm with CARP failover configuration.

Everything is setup like discribed in the how-to ans also works very well when i do a manual failover or a shutdown / reboot of the primary device.
But when i pull a cable out of the primary box, the second box only fails over this interface and the others stay active on the other box.

• For synchronizing i use a dedicated network port with crossover cable.
• Port 1 is WAN
• port 2 is LAN with VLAN tagged interfaces on it

In the logs you can see that at first the device does a failover for all interfaces by adding an +240 for priority but then suddenly removes this added prioroty value and takes back the not failed interfaces.

Here are the logs:

I´ve also disabled IGMP Snooping on the LAN faced switch. The WAN-faced switch between PF and DSL-Modem is blackbox.

Couldnt find anything related via search / google

Any help here appreciated
