  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Question lfd .. Excessive resource usage - Plesk not accessible

KiamOe

Basic Pleskian
I have a plesk server ‪CentOS Linux 7.5 Plesk Onyx 17.8.11. a period of about 10 hours I got these errors by mail:

lfd on domain.com: Excessive resource usage:

I get these errors related to various webspaces

The process in question is php-fpm: master process

Resource: Virtual Memory Size
Exceeded: 577 > 512 (MB)
Executable: /opt/plesk/php/7.2/sbin/php-fpm

I have stopped and started the apache service, but no change.
I have stopped and started the plesk service, but no change.
I have stopped and started fail2ban, and no change.

There are some other possibly alarming issues:
I get: "Suspicious process running under user".... postfix/popuser and a few as nginx

Not sure what to do here... restart the server and see of plesk comes back up? Any ideas?
 
Actually, these messages are not from Plesk. This is from LFD/CSF - a 3rd party firewall that is not a part of Plesk installation.
The reason for such messages is that execution time alarm level "PT_USERTIME = "1800" in /etc/csf/csf.conf was exceeded by apache or other services.

In order to exclude apache from notifications you can try to perform the following steps:

1. Add the row "exe:/usr/sbin/httpd" to file /etc/csf/csf.pignore
2. Restarted csf and lfd:

# csf -r
# service lfd restart
 
Thanks IgorG! I'll give this a try... but since these errors appeared.. I can't login to plesk either, what could that be? What error log fil to look for this plesk issue?
 
I get no error at all. Connection timed out...
I tried to disable the firewall "systemctl disable firewalld" but it did not change anything.

What's the most relevant log file to look at?
