> In Kubernetes Application Mode, when there is significant etcd latency or
> instability, the Flink JobManager may enter a deadlock situation.
> Additionally, TaskManager pods are not cleaned up properly, resulting in
> stale resources that prevent the Flink job from recovering correctly. This
> issue occurs during frequent service restarts or network instability.
