Analysis and suggested fixes are AI-produced; please verify before acting on them._ **Status:** Open: no fix PR **Subject:** `QueryVirtualStorageTest.testQueryTooMuchData` (embedded-tests, `unit tests (25, N*,Q*)`) **Failures:** 1 · **First seen:** 2026-10-08 · **Last seen:** 2026-10-08 ### Root cause The query fails as intended, but the assertion at `QueryVirtualStorageTest.java:166` requires the exact message `Unable to reserve bundle`. With a 1 MiB cache and `virtualStorageLoadThreads` set to the CPU count, which reservation runs out of space first depends on thread timing. `PartialSegmentMetadataCacheEntry` throws `Unable to reserve bundle[...]`, `SegmentLocalCacheManager.reservePartial` throws `Unable to reserve partial metadata for segment[...]`, and the full-load path throws `Unable to load segment[...] on demand`. All three are `CAPACITY_EXCEEDED`, but only the first one passes the test. The failing commit (#20508) changes only Dart worker discovery, and the job passed on the neighbouring master commits. ### Suggested fix Assert on what all three capacity errors share: the `CAPACITY_EXCEEDED` category, or the substring `ensure enough disk space has been allocated`. Don't match the bundle-specific message, and include `t.getMessage()` in the assertion message so a future mismatch shows the actual error. ### Occurrences Failed push-triggered master jobs only. The daily triage routine adds one row per new failed job. | Date | Commit | Job | Failure log | Detail | Reported in | |---|---|---|---|---|---| | 2026-10-08 | 3cedc8ad05 (#20508) | `unit tests / unit tests(main) (25, N*,Q*) / test-jdk25-[N*,Q*]` | [job 113564498218](https://github.com/apache/druid/actions/runs/37851277426/job/113564498218) | `expected: <true> but was: <false>` at line 166 (message lacked `Unable to reserve bundle`); single attempt, no surefire retry | | -- This is an automated message from the Apache Git Service.
