In Confluence, new and modified content is placed in the index queue, which, by default, is flushed once every five seconds.
Furthermore, whenever you publish with Scroll Versions, Scroll Versions automatically triggers the index queue to be flushed after the publish job is finished. Normally this works fine, but sometimes it causes error conditions where Confluence runs multiple index flush jobs at the same time – causing problems and slowing down the Confluence system.
If you are experiencing problems like these, you can disable Scroll Versions from flushing the index queue after publishing, and wait for Confluence's regular index flush to flush the new content from the index queue instead.
Disable Automatic Flushing
Disable automatic flushing after publishing jobs by navigating to General configuration > Advanced Scroll Apps Settings, and setting versions.publish.flushindex to false.
