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’.
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
