             Summary: Test failure: transient_replication_test.py::TestTransientReplicationRepairStreamEntireSSTable::test_optimized_primary_range_repair
                 Key: CASSANDRA-17685
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-17685
             Project: Cassandra
          Issue Type: Bug
          Components: Test/dtest/python
            Reporter: Andres de la Peña


The Python dtest {{transient_replication_test.py::TestTransientReplicationRepairStreamEntireSSTable::test_optimized_primary_range_repair}} is flaky at least in {{{}cassandra-4.1{}}}, with a flakiness < 1%.

I haven't seen the failure on Jenkins but on [this CircleCI run|https://app.circleci.com/pipelines/github/adelapena/cassandra/1663/workflows/c63703e3-8c7a-42c6-981a-53cb59babe1f/jobs/17476] for CASSANDRA-17458.

The failure can also be [reproduced in the multiplexer|https://app.circleci.com/pipelines/github/adelapena/cassandra/1666/workflows/6f925be1-c0df-4b2a-83e0-4612a46f32bd/jobs/17516], with 5 failures in 5000 iterations:

        it will be used internally.
    
        The other arguments are the same as for the Popen constructor.
    
        If universal_newlines=True is passed, the "input" argument must be a
