Large number of Azure subscriptions causes "available memory is almost depleted" error while launching application pattern - Known Error

Large number of Azure subscriptions causes "available memory is almost depleted" error while launching application pattern Description When running cloud discovery with a large number of Azure subscriptions and regions in one discovery schedule (4000+ subscriptions, all 47 regions) the instance will attempt to launch application patterns but will fail with an error:

"Transaction cancelled: available memory is almost depleted."

This results in no application patterns being launched.

Steps to Reproduce

On the customer instance this was always observed whenever a large cloud discovery schedule was launched.

Have been unable to reproduce on personal lab/employee instances.

Workaround The workaround for this is to modify the CloudResourceDiscoveryLaunch script include to batch groups of 500 service accounts together and launch the application patterns via a scheduled job.

This allows patterns to be launched in smaller batches, while still launching the patterns faster by utilizing multiple worker threads.
