Find out why job regression-validate-freeze fails in nightly regression.
**Summary of the defect**
The job regression-validate-freeze fails more frequently recently. I am thinking there might be something wrong hide behind it.

**How to reproduce (if possible)**
Just check hedera-services master branch's nightly regression. For example, this link: https://app.circleci.com/pipelines/github/hashgraph/hedera-services/1070/workflows/3245b8bc-1496-4f3d-b467-668734b9e897/jobs/13443.
