CARP Problem/Bug? on 10.1-RELEASE

Hi Steven,
you made my day! It's working again. But I continue my research.
Rebooting takes the Port-Channel on the switch down. When the machine
comes up the port-channel on the switch needs some seconds until it's
up. During that time, traffic is not forwarded. Sometimes I could see on
the console screen something like "send error 50 on vlan...... demoted
by 0 to 720... "
After setting "net.inet.carp.senderr_demotion_factor=0" I could see
still the message. But then the Interface is demoted from 0 to 0. With
this setting the "net.inet.carp.demotion" remains at 0. When the
Port-Channel on the switch is up packets are forwarded again. Then the
designated Backup machine goes back in the Backup state and machine 1 is
getting the master again.
So everything works now like expected!
I think these new "send error" feature makes some adjustment necessary
when using Link Aggregation or when the switch port takes some seconds
until it forwards the traffic (not using spanning-tree portfast feature).
It could be useful when the dev team would release some description how
the new carp features work together. The manual explains what parameters
you can set. But without understanding whats going on it gets some trial
and error. Maybe there is still a description and I didn't find it until
now.
Thanks for the help!
Best regards
Sascha
