报错分析,readAddress, connection time out。

报错日志片段

2021-06-09 17:42:53,873 ERROR
org.apache.flink.runtime.io.network.netty.PartitionRequestQueue [] -
Encountered error while consuming partitions

org.apache.flink.shaded.netty4.io.netty.channel.unix.Errors$NativeIoException:
readAddress(..) failed: Connection timed out

,如上是某个taskmanager的报错,30个taskmanager不好都去看。想知道这个异常指什么超时?需要做什么调整能改善呢。
