 rc.conf:
 
 ifconfig_em3="inet XX.XX.XX.XX/28 media 100baseTX mediaopt full-duplex"
 firewall_enable="YES"
 firewall_type="open"
 
 cloned_interfaces="carp0"
 ifconfig_carp0="vhid 20 advskew 140 pass heimLich XX.XX.XX.XY netmask 255.255.255.255"
 
 Script:
 
 #!/bin/bash
 while [ 1 ]
 do
 /etc/rc.d/netif restart
 sleep 30
 ifconfig carp0 destroy
 sleep 30
 done
 
 Crash after 10 minutes at 18:25h
 
 I append the first few lines of dmesg at the end.
