Sever Goes Down Cause Csf Firewall Blocks Everything

This weird issue has poped up only this weekend , when csf blocks all ips and even ssh, email and all services are not accesible, even though server is working, but firewall puts a block on everyone, and appears offline to others, any ideas why csf and iptables are not responding and acting in this behavior, i asked jonesolutions.com last time it happened i got no reason/response which could be the culprit.

Could it be the kernel update/upgrade that was done, to optimize load which broke csf and its working?

as this is 2nd incident over last 2 days , and i had thought my management had fixed it. Upset here over the unwanted for no reason downtimes!

Here is the output for this command after i restart csf again, and thats like average too i get over the entire day.

root@webhosting1 [~]# netstat -an |grep :80 |wc -l
188
root@webhosting1 [~]# netstat -an |grep :80 |wc -l
168

Connections to server dont seem to be high enough to pooch the firewall.
