Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Unbounded memory growth and Out-Of-Memory crashes can occur if already-terminating or done tasks are not skipped during clean-up sweeps, allowing tasks to pile up without being successfully reaped.
Denial of Service: Massive delayed-poll memory allocations during block decoding in the connector subsystem can trigger severe JVM heap crashes unless push-based memory reporting constraints are strictly enforced before block processing.
