The LFD service sometimes send excessive resource usage alerts as below:
Time: Tue Nov 19 09:41:10 2013 +0530
Resource: Virtual Memory Size
Exceeded: 205 > 200 (MB)
Command Line: /usr/bin/php /home/xxxxxx/public_html/index.php
PID: 24933 (Parent PID:22578)
The above alerts are received when a process utilizes more than the memory defined in the CSF configuration file under PT_USERMEM variable.
The changes in the memory value can be made by updating PT_USERMEM value in the CSF configuration file. To turn of these tracking, set value of PT_USERMEM to 0 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
Such alerts are useful to track the processes/accounts consuming high resources. Increasing the PT_USERMEM value and monitoring the processes should provide clear picture of resource usage.
