Hello,

I have CSF installed and updated to version 9.26 on a Centos VPS. Currently my CSF status Firewall Status is Enabled but Stopped. When I try to start the Firewall, I get the error "iptables: Memory allocation problem" and "Error: FASTSTART: (TCP_IN IPv4) [] [iptables-restore: line 26 failed]. Try restarting csf with FASTSTART disabled, at line 4904"

I am new to using CSF and do not understand how to resolve this issue in order to start the firewall. Please advise, thanks

HI! After the last update v10.15 my server isdown if I Start the CSF...

In email i recived similar alert to this post.. My server is centos with cpanel. and now my CSF version is 10.16

/usr/local/bandmin/bandmin
iptables: Memory allocation problem.


In CSF system logs see this alert:

Jul 25 01:15:10 XXXXX lfd[16383]: csf is currently restarting - command [/sbin/iptables -L LOCALINPUT -n] skipped on line 2778
Jul 25 01:15:10 XXXXX lfd[22919]: csf is currently restarting - command [/usr/sbin/exim -bpc] skipped on line 3086
Jul 25 01:15:12 XXXXX lfd[16383]: TERM

After its the server was down. Then I restarted the server and saw the csf "stop"..
I Try restart but recibed this alert in iptables logs:
