The test count_secondaryok.js fails deterministically in the sharding_config_shard suite because it stops the only primary in rs0, leaving the cluster without a reachable primary.

During teardown, ShardingTest.stop() runs the routing-table consistency hook, which makes a call against the config primary with primary read preference. Because the cluster no longer has a primary, that call times out during host selection after roughly 15 seconds and fails with FailedToSatisfyReadPreference. The exception then propagates out of ShardingTest.stop(), causing the test itself to fail.
