Summary
Pdf export fails while using Scroll PDF exporter. This might occur during export to PDF of large spaces. The export might fail partially and get stuck at some point, like 40-50%.
Environment
6.3.4 - Reached End of Life
.
Diagnosis
If the K15s scroll PDF exporter is used, instead of Confluence's default pdf exporter, this error could occur and the user might come across the following error messages in the atlassian-confluence.logs:
2020-10-12 14:22:36,645 ERROR [scroll-pdf-export:thread-3] [scroll.exporter.job.ExportJobRunnable] run Exception during export.

If the space being exported is large, this error can occur. This is because K15 Scroll Exporter does not apply segmentation mode, where the file is split into different parts and exported. This could cause a timeout if the file is large. There is an option in the Scroll PDF exporter to apply segmentation mode, which could help avoid this pattern.
Solution
For bugged exports, enabling the "segmentation mode" feature in Scroll PDF Exporter can lower memory usage and increase performance for large exports.
