PFTB-351 — PF table rebuild failed
An IOCTL operation for PF table reconstruction failed.
A typical reason is that the system tunable variable net.pf.request_maxcount is set to a value lower than %1. The problem of setting this variable is that it is marked as read-only and can be set only in the /boot/loader.conf file. This change takes place only after the next reboot.
Add line net.pf.request_maxcount=new_value (higher than %1) to the /boot/loader.conf file and reboot.
