This test has failed 8% of the time since start of December, see https://develocity.apache.org/scans/tests?search.rootProjectNames=solr-root&search.timeZoneId=Europe%2FOslo&tests.container=org.apache.solr.search.TestQueryLimits&tests.sortField=FLAKY&tests.test=testAdjustShardRequestLimits <img width="1257" height="373" alt="Skjermbilde 2025-12-10 kl 16 24 18" src="https://github.com/user-attachments/assets/ee701285-f5ef-42b1-85c4-90d1e6f496ce"; /> My AI buddy believes it fails due to a too low timeAllowed in the initial request: ## Root Cause The test was failing due to a timing race condition in distributed grouped queries: 1. Test Setup: Uses timeAllowed=500ms with sleep=100ms per request 2. Grouped Query Phases: Distributed grouped queries require 2 phases 3. Actual Timing (from failed run logs): - Phase 1: ~100ms (matching sleep) - Phase 2: ~436ms (sleep + query processing, especially term iteration) - Total: ~536ms > 500ms timeout 4. The Issue: The 500ms budget was barely sufficient: - 200ms consumed by sleep operations - Only 300ms margin for query processing, network overhead, and system variability - Phase 2 query processing (term iteration in SolrRangeQuery) is variable and can exceed this tight margin -- This is an automated message from the Apache Git Service.
