    How can I disable the email alerting me to server load average being high? We are running CPU intensive software on some of our servers and its getting annoying have the emails streaming in.

    You can also setup email filters to group and manage these alerts which is better than disabling all alerts.

    Also check CSF Firewall's config /etc/csf/csf.conf and official docs/readme linked at bottom of CSF Firewall - CentminMod.com LEMP Nginx web stack for CentOS ? hint custom via csf.pignore ;)
    another hint check options related to LF_ALERT_*, PT_LOAD* and references to csf.pignore

# The following is a list of executables (exe) command lines (cmd) and

#
# You must use the following format:
#
# exe:/full/path/to/file
# user:username
# cmd:command line
#
# Or, perl regular expression matching (regex):
#
# pexe:/full/path/to/file as a perl regex[*]
# puser:username as a perl regex[*]
# pcmd:command line as a perl regex[*]
#
# [*]You must remember to escape characters correctly when using regex's, e.g.:
# pexe:/home/.*/public_html/cgi-bin/script\.cgi
# puser:bob\d.*
# pcmd:/home/.*/command\s\to\smatch\s\.pl\s.*

# It is strongly recommended that you use command line ignores very carefully
