Since we migrated some our jobs to OCP 4.14, we are experiencing a lot of flakiness with the "openshift-tests" binary which panics when trying to retrieve the logs of etcd: https://prow.ci.openshift.org/view/gs/origin-ci-test/pr-logs/pull/openshift_assisted-test-infra/2212/pull-ci-openshift-assisted-test-infra-master-e2e-metal-assisted/1673615526967906304#1:build-log.txt%3A161-191

Here's the impact on our jobs:

 N/A

Happens from time to time against OCP 4.14

1. Provision an OCP cluster 4.14
2. Run the conformance tests on it with "openshift-tests"

The binary "openshift-tests" panics from time to time:
