  The SAP error message DB11182, which states "Event not within top ten wait events," typically indicates that a specific database event is not among the top ten wait events that the database is currently experiencing. This message is often related to performance issues in the SAP system, particularly in the context of database performance monitoring and tuning.
  Cause:
