> I deploy flink cluster and it run normally about 2 months, but recently i
> meet a problem. I see some sub tasks back pressure is high and the flink job
> is totally blocked(in pic1.jpg), these sub tasks are all in one task manager.
> so i stop the abnormal task manager and deploy flink job again, the problem
> is solved. I find some error log in the abnormal task manager:
> 2024-03-03 15:57:25,088 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
> What does it mean? What should i do to solve this problem completely?
