Potential problems:

  1. Measured document hit ratio (31.42%) differs from the offered DHR (37.82%) by -16.92%.
  2. Measured byte hit ratio (32.50%) differs from the offered BHR (39.00%) by -16.67%.
  3. Reported fill count contribution (40.73%) does not match `cachable miss' estimation (49.20%).
  4. Reported fill volume contribution (42.82%) does not match `cachable miss' estimation (51.41%).
  5. Error ratio (12.65%) exceeds 0.10%.
