Apr 1, 2026April 2026 Milvus: Stability and reliability improvements in test teardown for parallel execution. Fixed a SIGABRT crash in the ChunkManagerWrapper destructor during parallel test teardown by switching to the Boost filesystem remove_all() overload with error_code to gracefully handle errors. The fix was applied consistently across all affected test utilities (storage_test_utils.h, InvertedIndexTest.cpp, JsonFlatIndexTest.cpp) and linked to commit e982662c896b7f3a0957c44ecdbbcdca8ac2f226 (PR #48834). Resulting in a more robust CI pipeline and reduced test flakiness during parallel shards.
