Jira issue: CRDB-67968

Start with the TeamCity build log and artifacts linked in the issue for pkg/kv/kvserver/liveness/liveness_test_/liveness_test on s390x. Investigate whether the test binary failed to execute because of a Bazel timeout, an init() issue, or another reported error; done means identifying and fixing the cause so the package test passes on that platform.
