Sewer Pipe Cracking Concern

[Kevin Gallagher]

I had a sewer line inspection today at a property I have under contact. The scope showed a couple longitudinal cracks slightly less than 1 ft in the cast iron pipe under the foundation. The pipe also had a good bit of rust. Otherwise was clear. House is 50 years old.

Do either of these seem like concerns? Does this type of cracking in cast iron pipe raise any red flags?
