Question

Why am I receiving email notifications with subjects such as the following?

lfd on $hostname: Excessive resource usage: $username

Answer

These notifications are generated by the 3rd party software ConfigServer LFD, not cPanel. The resource usage limits can be modified by changing the PT_USERMEM and PT_USERTIME settings from the "Firewall Configuration" settings of "ConfigServer Security & Firewall" in WHM.

Alternatively, you can configure LFD to ignore certain processes or users in the /etc/csf/csf.pignore file.
