Recurring patterns

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

Denial of Service: Unsynchronized updates to shared memory counters across asynchronous tasks allow race conditions, potentially leading to incorrect state tracking and memory exhaustion or crashes.
Denial of Service: The use of multiprocessing.Manager proxies for sharing state between server handlers can lead to severe system resource leaks and eventual server denial of service under sustained loads.
