How to disable Lfd excessive resource usage alert ?

Example mail : 

Time: Tue Nov 25 09:15:10 2012 +0520
Account: username
Resource: Virtual Memory Size
Exceeded: 205 > 200 (MB)
Executable: /usr/bin/php
Command Line: /usr/bin/php /home/username/public_html/index.php
PID: 11254 (Parent PID:11254)
Killed: No

Method I
You can disable this particular feature from CSF configuration. That’s not a good method to solve this issue. This email alert is actually much useful for monitoring user’s resource usage under your server.
How to disable it?
Step 1: Login to your server via SSH as root user.
Step 2: Open the CSF configuration file (/etc/csf/csf.conf) with your favorite editor and search the directive ‘PT_USERMEM’. By considering the above example, the PT_USERMEM is 200. You can set the value of PT_USERMEM to ‘0’ to disable this feature from CSF.
[root@server #] vim /etc/csf/csf.conf
-----
# This User Process Tracking option sends an alert if any linux 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 = "200"
-----


Method II
You can increase the PT_USERMEM limit. By setting the value of PT_USERMEM to a higher value than 200 may help you.

Method III
This is the simplest and standard way to stop such alerts from CSF and LFD. There is a file in csf directory ‘csf.pignore’. You can add the process or the user which you want to ignore this type of alert in to this file.
File location:
[root@server #] vim /etc/csf/csf.pignore


Note:
This type of alerts are useful for monitoring your server. 


Restart the services CSF and LFD
csf -r
