Issue/Introduction

Clarity app service crashes with OutOfMemory error, when reviewing the heap dump we see there is more than 1GB taken by:
GET /reportservice/rest_v2/export/3xxxxx-dff0-xxxx-b6f3-xxxxxxxxx/MyFolder-export.zip

This is due to a very large reports folder exporting at once.

Resolution

DE48757 Jaspersoft folder export from Clarity Advanced Reporting  crashes the app with OutOfMemory when doing a large export.zip
Will not Fix as per Engineering
We recommend to export the files in small chunks for now. We're looking for a good way to make this work whilst avoiding a system outage.
