Issue
- A `DuplicateFileEntryException` error occurs when starting a clustered DXP instance after a virtual instance is created, even if the file already exists in the Document Library. The error, seen in the logs, resembles the following:
INFO [ajp-nio-0.0.0.0-8009-exec-13][BundleSiteInitializer:443] Initializing com.liferay.site.initializer.welcome for group <groupId> ERROR [ajp-nio-0.0.0.0-8009-exec-13][BundleSiteInitializer:634] null com.liferay.document.library.kernel.exception.DuplicateFileEntryException: A file entry already exists with title astronaut.png - Clearing the temp and state folders does not resolve the error.
Environment
- Liferay DXP 7.4 Quarterly Releases
Resolution
The root cause is the site initializer attempting to run on virtual instances with no public pages. Creating a public page for each virtual instance will resolve the issue.
