# Very high server load average after upgrading Qdrant to v1.14.0 with batch search

## The problem

After upgrading a test server from Qdrant v1.13.6 to v1.14.0 (56-CPU machine), server load average spiked dramatically while running batched search queries (100-1000 queries per batch) interleaved with blocking vector updates. The reporter tried tuning incremental_hnsw_building, max_optimization_threads, max_indexing_threads, and update_rate_limit without effect. Metrics showed grpc SearchBatch avg duration rose more than 10x after the upgrade.

## The verified fix

The maintainers reproduced and confirmed this as a regression in v1.14.0 related to batched search (suspected PR #6326). The fix shipped in the v1.14.1 patch release; maintainer timvisee confirmed on the thread that 1.14.1 includes the patch for this problem. Resolution: upgrade to Qdrant v1.14.1 or later. The reporter's workaround of reverting to v1.13.6 also eliminated the spike, confirming the version-specific cause. Source: https://github.com/qdrant/qdrant/issues/6423
