> In our cluster, there has been an issue of duplicate registration of queue
> metrics, causing the Resourcemanager to fail and exit. Through code analysis,
> it is possible that adding the synchronized keyword is required when
> registering the metrics queue method. !image-2023-10-08-15-12-49-688.png!
