In a setup of two redundant carp firewalls, each serving four
interfaces, the master crashes regularly (but not always) after a
manuall failover from the backup to the master.
This is how I do the manual failover ('carpdown' on master):
---snip---
for i in 0 1 2 3; do ifconfig carp$i down; done
ifconfig | grep "carp:"; sleep 1
for i in 0 1 2 3; do ifconfig carp$i destroy; done
ifconfig | grep "carp:"
---snip---
After maintenance, I switch back from backup to the master ('carpup' on
master):
---snip---
for i in 0 1 2 3; do sh /etc/netstart carp$i; done
route add default 130.**.*.***
---snip---
It then would crash after a few seconds. Is this a known issue?
The server runs not much, except ftp-proxy, snmpd, sshd, ntpd and nrpe.
Please find dmesg, ps and trace below. Thanks for your help:
