Ipfw:Failed to get the max tables number via sysctl?

[zlyzwy]

Hi all,

I am receving the following error from console when PF is starting.

ipfw: Warn: Failed to get the max tables number via sysctl. Using the compiled in defaults. 
The reason was: No such file or directory
ipfw: getsockopt(IP_FW_TABLE_GETSIZE): Protocol not available

PF Version: 2.0.1-RELEASE (i386)
built on Mon Dec 12 18:24:17 EST 2011
FreeBSD 8.1-RELEASE-p6

Package Installed:
1. Unbound
2. FreeRadius2
3. Open-VM-Tools
4. pfBlocker
5. Cron
6. RRD Summary
7. Strikeback
8. vnstat2

I saw the same problem here:

There is no solution:(

Recently I was testing CP + FreeRadius2, but there is some problem so I disabled the CP.

Thanks for any reply!
