Aria Automation 8.18.x
With Aria Automation version 8.18.x new services have been added, however internal testing showed it was not required to extend the current Sizing Guidelines.
The default Aria Automation health check is configured to fail is the memory usage is larger or equal then 90%.
The configured alert in Aria Operations can therefor be adjusted or a the environment can be configured to use a higher profile.
If the environment is already configured with XL profile then more RAM can be added as required.
