大概不是显示bug,可以参考这个回答

我有一个数据源文件丢失了,但是这个任务还是绑定一个worker上,如何删除呀。
报错提示:
source=mysql-replica-stm-01] [expect=Running] [error="[code=38008:class=dm-master:scope=internal:level=high], Message: grpc request error, RawCause: rpc error: code = Canceled desc = context canceled"

使用命令:
» operate-source show
现在是一直卡住,如何下掉这个异常的task

DM-worker 和上游数据库无法连接了么 ? 可以 operate-source stop source-id 停掉。
