Consumed space on console server

Yesterday the following folder

\nexpose\nsc\temp\ingress

generated a 1million+ files and consumed 400GB. Can anyone explain what exactly this folder is doing and why we might have had such a spike?

This is most likely to do with extensible ingress and a failure with your console to communicate with the platform. If you check in the UI under the system notifications in the top right corner there should be an error message indicating some sort of communication issue.

Open a support ticket and they can direct you to the necessary commands to run and logs to pull to help troubleshoot and resolve this.
