> Key: SOLR-18202

> Project: Solr
> Issue Type: Test
> Reporter: Chris M. Hostetter
> Priority: Major
>
> * SolrIndexFingerprintTest was added to the (main branch) Solr codebase by
> SOLR-17756 ~ 2025-05-21
> ** it has always had a single test method:
> testSequentialVsParallelFingerprint
> * [Historical jenkins
> metrics|https://fucit.org/solr-jenkins-reports/history-trend-of-recent-failures.html#series/org.apache.solr.update.SolrIndexFingerprintTest.testSequentialVsParallelFingerprint]
> show that for the first ~3 months this test existed, it had a consistent
> (weekly) failure rate of 0%
> * Starting sometime just before ~ 2025-08-25, the weekly failure rate
> started to fluctuate between 0-3%
> ** This date corresponds with the changes introduced by SOLR-17863
> * Sometime during the week ending 2026-03-30, the weekly jenkins failure
> rate jumpted to ~ 10%, and seems to be staying there
> ** spot checking the logs of recent jenkins failures, the recent errors all
> seem to be OOM related.
