Pfr_unroute_kentry: delete failed.
We are seeing many of the above message on our HA backup system. What's odd is this HA pair have been operating for over a year without any issues and prior to this problem no changes to the configuration done. Primary has not had this problem.
Googling it appears to be a FreeBSD bug.
Rebooting the HA backup system brings it back alive for a couple days/weeks until it locks up with the same error.
Any suggestions would be appreciated.
