It is very common to see some cracking or leaning in a retaining wall. Generally, it is not a major concern and is often left as is. With that being said, there are some circumstances where consulting with an engineer is wise.
Similarly, What causes retaining wall to crack?
Collapsing/Tilting Retaining Walls
Railroad tie retaining walls can begin to collapse due to wood rot or deterioration. Most retaining walls require drainage “weeps”. If water accumulates behind the wall, this additional weight can cause clay soils to expand, leading to cracks and tilting.
Additionally, How do you tell if a retaining wall is failing? The three most common signs of a retaining wall in distress are (1) Leaning; 2) Cracking and 3) Bulging of the Wall or Segments.

What is a common reason for the failure of timber retaining walls?
The location of large trees close to the retaining wall. Poor drainage allowing the structure to be weakened by hydrostatic pressure. Heavy rain is a major cause of the retaining wall failure as the moisture causes reactive clay to expand and exert pressure onto the retaining wall which then can crack and fail.
