Editing Files
In this article you will be required to edit files. This documentation will use the vi text editor. When using the vi

- Press Esc to exit insert mode
- When you have finished, save the changes in vi by typing :wq and press Enter
Resolution
In larger deployments of Log Server, PHP needs the memory_limit increased from the default of 128M. This needs to be performed on all Log Server nodes. The following steps will increase the value to 512M.
Establish a terminal session to each Log Server node as a root user.
This change needs to be made to your php.ini file, to determine the location of this file execute the following command:
find /etc -name php.ini
If there are multiple results then the one in the apache directory is the one that needs changing.
Edit the file and make the following change:
memory_limit = 512M
Once the change has been made you will have to restart Apache for the changes to take effect using one of the commands below:
RHEL 7 + | CentOS 7 +
systemctl restart httpd.service
Debian | Ubuntu 16/18/20
systemctl restart apache2.service
Once the service has restarted, the Administration page will be accessible. If the problem persists, please increase the value again.
