in csf.pignore already, and restarted lfd. Even tried to reboot the whole server and nothing change. It seems lfd just ignores that file. It's v6.22 on a CentOS 5.9 - 64bits.
As I mentioned above, I even tried to restart the whole server, but after it's coming back, warnings still appear in my email. Have no clue why it's happening. I search on board and see some others have the same issue, that lfs seems ignore csf.ignore settings. Don't know where the bug is.
