  The SAP error message ESH_ADM_MSG158, which states "Queue with index &1 has not been flushed," typically relates to issues with the Enterprise Search (ESH) component in SAP. This error indicates that the index queue for a specific index has not been processed or flushed, which can lead to inconsistencies in the search results.
  Cause:
  
  Indexing Issues: The index queue may not have been flushed due to errors during the indexing process, such as data inconsistencies or failures in the data extraction process.
  System Performance: High system load or performance issues may prevent the queue from being processed in a timely manner.
  Configuration Problems: Incorrect configuration settings for the search index or the underlying data sources can lead to issues with flushing the queue.
  Locks or Transactions: If there are locks on the data or ongoing transactions that prevent the index from being updated, this can cause the queue to remain unflushed.

  Check Index Status: Use transaction codes like Esh_index or Esh_admin to check the status of the index and the queue. Look for any errors or warnings that may indicate why the queue has not been flushed.
  Flush the Queue Manually: If the queue is stuck, you may need to manually trigger a flush. This can often be done through the ESH administration tools or by executing specific background jobs.
  Review Logs: Check the application logs (transaction SLG1) for any error messages or warnings related to the indexing process. This can provide insights into what went wrong.
  System Performance: Monitor system performance and resource usage. If the system is under heavy load, consider scheduling the indexing process during off-peak hours.
  Configuration Review: Review the configuration settings for the search index and ensure that they are correctly set up. This includes checking data sources, extraction settings, and index settings.
