> Connection timed out, Standalone cluster
> ----------------------------------------
>
> Key: FLINK-15074
> URL: https://issues.apache.org/jira/browse/FLINK-15074
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Network
> Affects Versions: 1.9.1
> Environment: flink version : 1.5.1 , 1.9.1
> jdk version : 1.8.0_181
> Number of servers : 15
> Number of taskmanagers : 178
> Number of slots: 178
> Reporter: gameking
> Priority: Major
> Attachments: flink-conf.yaml, jobmanager.log, taskmanager.log
>
>
> I am running a flink streaming application on a standalone-cluster.
> It works well when the job's parallelism is low, just like 96.
> But when I try to increase job's parallelism to a high value, like 164 or more, Job will fail in 10-15 minutes due to connection timeout error
> I have try to solve this problem by increaseing taskmanager configs just like 'taskmanager.network.netty.server.numThreads', 'taskmanager.network.netty.client.numThreads', 'taskmanager.network.request-backoff.max', 'akka.ask.timeout' and so on, It doesn't work.
> I also try to change different versions of flink, such as 1.5.1 and 1.9.1, to solve this problem , it doesn't help too.
> Does anyone know how to fix this problem，I have no idea now. It looks like a bug.
> I hava upload my config and log as attachment, and the error trace below ：
