that is all ok, add it to csf process ignore list
/etc/csf/csf.pignore

Are you sure it's normal? We have install cwp 1 years ago. First time getting this errors.
We have another cwp server. Its not showing errors like that.

Please explain what cwpsvc is doing? top -u cwpsvc command always showing 2 process. 1 hour later its ending and starting again. another server showing nothing.

yes 100%

cwpsvc is a process that is used for cwp services like for example roundcube and phpmyadmin, if you have high activity there then you should check if maybe you have some brute force attack there.

you can check cwp logs for that

note that this is UDP traffic coming to custom ports and that isn't something that would be show cwpsvc as a process since cwpsvc is using cwp ports and TCP traffic

great, you can simply block that ip with csf, example:
Code: [Select]
csf -d <IP> "pma brute force attack"
