pfSense

We are running a carp failover bundle in the same network with a
vrrp router pair and therefore we get a lot of unnecessary log
messages (carp_input: received len 24 < sizeof(struct carp_header) on em3)
when the pfsense machine sees vrrp traffic.
To get rid of those messages we decided to set net.inet.carp.log=1 in System
Tuneables.
When adding the setting in the web interface it is applied correctly and the
messages disappear until one of the following happens:

• the machine is rebooted (the settings are ignored here)
• you press save in carp settings (net.inet.carp.log gets set to 2 here)
• on the slave it is reset to 2 on every config sync
