tl;dr: A Codex bug caused its SQLite feedback log to write at extreme rates—roughly 37 TB over 21 days on one user's machine—due to a global TRACE-level default that persisted noisy dependency logs, raw WebSocket/SSE payloads, and mirrored OpenTelemetry events. Analysis showed ~96% of retained log bytes came from TRACE noise and otel mirror logs, with heavy insert-and-prune write amplification (5.5B row IDs allocated for only 0.5M retained rows). Two merged PRs now filter noisy targets and stop logging every Responses WebSocket event, eliminating about 85% of logs.
