how to increase virtual memory size? Help needed

| I've been receiving notifications like this:
Excessive resource usage
Resource: Virtual Memory Size
Exceeded: 114 > 100 (MB)
Can you please teach me how I can increase VM size? It's a dedicated server with centos and cPanel installed
My tweak settings is set to 256MB

| It is a php error?
if so look in the /etc/php.ini file.
or apache /etc/httpd/conf/httpd.conf file.

| nevermind, I figured that I had to adjust a setting in CSF.
But how does ulimit -v work? I set it to to like 250MB but when i checked virtual is still showing as unlimited

| Best practice is to create a swap partition that will use for virtual memory, swap partition is always double of your RAM.
here are some steps
1. make a partition with fdisk and change its type -> 82
2. reload partition table with partprobe.
3. if your swap partition is /dev/sda3, you type mkswap to make it swap parition
#mkswap /dev/sda3.
4. turnon swap
#swapon /dev/sda3.
5. define in /etc/fstab like that it effect next reboot wont required to active it again.
/dev/sda3 swap swap defaults 0 0

| Edit /etc/csf/csf.conf
Find this PT_USERMEM = "100" and change it to 256 or 0(to disable notifications)
PT_USERMEM = "0"
