pfBlockerNG Cron Kills all my connections

[Soloam]

Hello, for some time I have been having some random drops in connections, sometimes my ssh drops, of some tcp connection drops, and I was not able to discover the reason. Now I discovered that all my active connections just are dropped when "pfBlockerNG Cron" runs. If I run "/usr/local/bin/php /usr/local/www/pfblockerng/pfblockerng.php cron" all my connections are dropped.

I reference @BBcan177 to see if he knows any possible reason. But if any one had similar problems, please tell me!

In my system logs I see:

Apr 29 20:01:02	php		[pfBlockerNG] No changes to Firewall rules, skipping Filter Reload
Apr 29 20:00:25	check_reload_status		Reloading filter
Apr 29 20:00:25	php		/usr/local/www/pfblockerng/pfblockerng.php: The command '/sbin/ifconfig 'em0.9' delete '10.10.10.1'' returned exit code '1', the output was 'ifconfig: ioctl (SIOCDIFADDR): Can't assign requested address'
Apr 29 20:00:25	php		[pfBlockerNG] Starting cron process.

At this time my connection dropped

Any idea?
Thank You
