  The SAP error message DB6104, which states "The buffer pool size is &1," typically relates to issues with the database buffer pool configuration. This error can occur in various SAP database systems, particularly when the buffer pool size is either too small or not configured correctly for the workload.
  Cause:
  
  Insufficient Buffer Pool Size: The buffer pool may be too small to handle the current workload, leading to performance issues and increased disk I/O.
  Configuration Issues: The buffer pool size may not be set correctly in the database configuration settings.
  Database Limits: The database system may have limits on the maximum size of the buffer pool that can be allocated.
