> {{CheckRepositoryTestBase#corruptRecord}} corrupts a {{NODE}} record by writing random bytes inside. Currently when a corrupt node {{/z}} is traversed by the consistency check the traversal will fail with the following message {{Error while traversing /z: null}}. Most likely the corruption stems from an attempt to read an out of bounds segment reference [1]. The log message in {{ConsistencyChecker}} should be changed to include the root cause and the reason of the traversal failure.
