Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Denial of Service: High logging volume can cause a memory leak and process crash if internal Node.js stream state flags (specifically the synchronous state flag) are not correctly reset before invoking callbacks. This disrupts application availability under heavy production loads.
