…open files" error Fixes #293. Users experienced "Too many open files (os error 24)" during indexing because CocoIndex's default concurrency (1024 inflight rows) opens more file handles than OS limits allow (typically 256-1024). Set COCOINDEX_SOURCE_MAX_INFLIGHT_ROWS=256 in both code paths that invoke cocoindex (pipeline.run_cocoindex_update and server._cocoindex_subprocess_env).

Summary
COCOINDEX_SOURCE_MAX_INFLIGHT_ROWS=256before invoking cocoindexjava_codebase_rag/pipeline.pyandserver.pyRoot Cause
CocoIndex's default concurrency (1024 inflight rows) opens too many file handles simultaneously, exceeding OS file descriptor limits (typically 256-1024). This is not user error - even with fresh OS startup and single terminal window.
