Linux 6.8 or 6.10 Operating System Settings
The following settings are recommended to accommodate the size and complexity of ACSLS. Use the following guidelines to apply the appropriate settings based on the size of your system:
-
Small system: 64 GB RAM or less
-
Medium system: 64 GB to 128 GB RAM
-
Large system: Greater than 128 GB RAM
Specify settings in the file /etc/security/limits.d/90-nproc.conf.
Once these values are set, you must reboot the ACSLS server using the reboot -p command.
