DB6155 - Details

• The SAP error message DB6155, which states "The percentage of the dirty page steal cleaners is too high," typically relates to issues with the database's memory management, particularly in the context of the SAP HANA database or other databases that SAP might be using. This error indicates that the system is experiencing a high percentage of dirty pages, which are pages in memory that have been modified but not yet written to disk.
