LFD Excessive Resource Usage Alerts

The LFD service sometimes send excessive resource usage alerts as below:

Time:    Thu Nov  5 12:25:47 2015 -0500
PID:     486516 (Parent PID:485265)
Account: xxxxxx
Resource: Virtual Memory Size
Exceeded: 210 > 200 (MB)
Executable: /usr/bin/php
Command Line: /usr/bin/php /home/xxxxxx/public_html/index.php
PID: 24933 (Parent PID:22578)
Killed: No

Normally these alerts received when a process utilizes more than the memory defined in the CSF configuration file under  PT_USERMEM variable.

Previously we have talked about how to disable these Alerts But personally in my opinion Such alerts are useful to track the processes/domains consuming high resources. Increasing the PT_USERMEM value and monitoring the processes should provide clear picture of resource usage.

We can change the memory value limits by updating PT_USERMEM value in the CSF configuration file

1)  Login in the server as root user.

2) Open the CSF configuration file


3) Locate PT_USERMEM in the file and set the desire value.

4) Restart CSF

csf -r

There is a file in csf directory ‘csf.pignore’. You can also add the process or the user which you want to ignore this type of alert in to this file.

nano /etc/csf/csf.pignore
