The content processing pipeline failed to process the item.

Hi @Rui Pinto Ferreira ,

The error message "The content processing pipeline failed to process the item" typically indicates issues with the SharePoint Search service, particularly related to the content processing component. This can occur due to several reasons, including:

1. Insufficient User Rights: The service account for the Windows Service – Search Host Controller Service may lack the necessary user rights. Specifically, it needs:
   • SeAssignPrimaryTokenPrivilege: Allows the Search Component to modify the security access token of the ParserServer.exe process.
     • SeIncreaseQuotaPrivilege: Allows the Search Component to adjust the memory quota of the ParserServer.exe process.
     1. Parser Server Workers: If all parser server workers cannot restart, it may indicate that the pool has no more workers available. This can be caused by:
        • Broken communication between the parser server and the content processing component.
          • Excessive resource usage leading to time-outs.
            • Permission issues with required directories or configuration files.
2. Network Issues: If there are network communication problems between the crawl server and the content server, it can block the crawl, leading to errors.
3. ULS Logs: Review the ULS logs on the server hosting the content processing component. Look for entries related to the parser server failing to start.
4. Check for Updates: Ensure that your SharePoint servers are up-to-date with the latest patches and updates.
