Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Unbounded resource utilization and memory leaks occur when utilizing unconstrained Eventlet concurrency abstractions or failing to mirror server packet size boundaries to the underlying WebSocket driver. This allows remote clients to exhaust server memory.
Denial of Service: Concurrency race conditions in the server socket registry can cause background runner tasks to crash when a socket is deleted by a parallel connection handler, leading to complete service disruption.
