  The SAP error message /SDF/DB6157 indicates that the percentage of dirty pages in the database has exceeded a predefined threshold. This situation typically arises in SAP systems that use the SAP HANA database, where "dirty pages" refer to pages in memory that have been modified but not yet written to disk. When the percentage of these dirty pages becomes too high, it can lead to performance issues and potential data loss if not addressed.

  Insufficient I/O Capacity: The underlying storage system may not be able to keep up with the rate of writes, causing a backlog of dirty pages.
