How to disable Lfd excessive resource usage alert?

Step 1: Login to your server via SSH as root user.
Step 2: Open the CSF configuration file (/etc/csf/csf.conf) with your favourite editor and search the directive ‘PT_USERMEM’.

nano /etc/csf/csf.conf

Set the value of PT_USERMEM to ‘0’ to disable this feature from CSF (see below).

# This User Process Tracking option sends an alert if any cPanel user process
# exceeds the memory usage set (MB). To ignore specific processes or users use
# csf.pignore
# 
# Set to 0 to disable this feature

 PT_USERMEM = "0"

 

And then restart CSF

csf -r
