-----------------------------------------
Summary: Scary uptick in failures from SolrIndexFingerprintTest
(OOM risk)
Key: SOLR-18202
URL: https://issues.apache.org/jira/browse/SOLR-18202
Project: Solr
Issue Type: Test
Reporter: Chris M. Hostetter
* 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.
