lfd.service: main process exited

Post by BuycPanel Admin »

Hello,

The following happens every day and I'm not sure why. Could someone explain the purpose of this? Is this intended, or is it an error?
How can I prevent it from happening, and is that recommended?

Daily in /var/log/cron:

Hello,

Same problem here withe cPanel/Cloudlinux7

Mostly at 00h01 but there also some randome times that is killed

We also have faced a total lockout server pinging ok but locked out without able to connect to SSH/cPanel/Websites after we "Edit csf.allow" and added an IP and restarted the CSF/LDF

To fix it we had to rename etc/csf/ directory, reboot the server then uninstall CSF and installit again because we had no "Console" to execute the commands on our Datacenter, but we had an external access to mount the disck to manually rename to force CSF/LFD fail on boot.

Here is the log wen I was locked out:

Another app is currently holding the xtables lock. Perhaps you want to use the -w option?

Same problem here, but not a Cpanel server, just CentOS7 standard install.
This issue started for me after an update of CentOS7, but back then a Google search revealed no matches.

The same error is logged when doing a manual "csf --restartall".

Same issue here, cPanel is able to restart the service, but I'm curious why it gets killed in the first place.

Looks like I have too many IP blocks (iptables busy waiting), and the csf.error mentions I should use IPSET. Guess that will be the solution.
