Spring-cloud-netflix: Hystrix - Caused by: java.util.concurrent.TimeoutException:

Created on 24 Jan 2018  ·  22Comments  ·  Source: spring-cloud/spring-cloud-netflix


I am on Spring Cloud Edgware.RELEASE trail.
I am using ribbon with Eureka.
I have @EnableFeignClients annotation on my API Gateway.
I am overriding the timeout configurations as below.
`

ribbon.ReadTimeout=30000
ribbon.ConnectTimeout=30000
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=100000

`
Even then, APIGateway is throwing the timeout exception.
The service is processing the request in good time only but API Gateway is not considering it.
This happens like once in 2 requests. Very random.

Please suggest if I miss any configuration.

Upgrading Zuul alone improved the connectivity issue. But still, I am getting the below exceptions in Zuul server.

`
Caused by: org.apache.http.conn.ConnectTimeoutException: Connect to 172.31.47.91:8000 [/172.31.47.91] failed: connect timed out

I Have the below configs in Zuul now.
ribbon.eureka.enabled=true
zuul.host.connectTimeoutMillis=600000
zuul.host.socketTimeoutMillis=600000

30 seconds timeout

ribbon.ReadTimeout=30000
ribbon.ConnectTimeout=30000
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=100000

I assume when you say API Gateway you mean Zuul, right?

yes, @ryanjbaxter

If you use Edgware.SR1 your above configuration should work. See https://github.com/spring-cloud/spring-cloud-netflix/pull/2633. We are making some improvements to this though, see https://github.com/spring-cloud/spring-cloud-netflix/pull/2645.

Should I just upgrade Zuul Server to Edgware.SR1 and leave the Eureka Server and clients to Edgware.RELEASE?
Does Eureka should also have this timeout settings in configuration?

You can move just the Zuul app if you want, but we always recommend you upgrade if you can. The configuration just needs to be in Zuul.

Thank you so much @ryanjbaxter
I have been banging my head on this issue. I would try upgrading Zuul to SR1 and keep these settings for Zuul alone.

Please learn how to format code on GitHub.

Can you provide the complete stacktrace? What do you mean it improved the connectivity issue?

Earlier I was getting connection timeouts for once in 2 requests. Now it is like once in 4 requests.
Here is the complete stack trace.

dulimitta picture dulimitta on 24 Jan 2018

This no longer has to do with Hystrix, its just the Apache HTTP Client timing out, have you tried adjusting your timeout settings?

ryanjbaxter picture ryanjbaxter on 24 Jan 2018

yes I did. I would spend more time on it now. Thanks for your help @ryanjbaxter

dulimitta picture dulimitta on 24 Jan 2018

@dulimitta I also have the same problem as you.
Have you got any update?

trngan picture trngan on 18 Apr 2018

yes @trngan the issue was not related to the Hystrix (thanks to @ryanjbaxter for guiding me in the right direction). It was an access issue. The Zuul API Gateway was not able to connect to the other services. After fixing the access issue, it worked like a charm.

Hi @dulimitta , i have the same exception in my own Zuul API Gateway. What do you mean with an access issue? How did you resolve the problem exactly?

Thanks!!

Hi @rodrite , the issue was not with Spring Cloud. The APIGateway had access issues connecting to client services. I fixed the access issues.

Hello @dulimitta , I am also facing same, can you please give some more details about how you fix this issue.

akhilajay picture akhilajay on 6 Oct 2018

Hello @ryanjbaxter I am also facing similar issue. instead of "Caused by: java.lang.RuntimeException: org.apache.http.conn.ConnectTimeoutException: Connect to 172.31.9.14:8003 [/172.31.9.14] failed: connect timed out" issue what I am getting is
"Caused by: java.lang.RuntimeException: org.apache.http.NoHttpResponseException: 192.168.1.100:8000 failed to respond"

all my microservices are running. this is happening sometimes only not all time. mostly 1 out of 10.

akhilajay picture akhilajay on 6 Oct 2018

It’s hard for me to help based on just that information. Please open another issue with a sample that reproduces the problem.

ryanjbaxter picture ryanjbaxter on 6 Oct 2018
  1. I have similar issues only on startup and always getting Timeout exception.
  2. If I disable, only the below hystrix flag then it works fine on startup as well.
feign:
  hystrix:
    enabled: true

hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds: 210000

but we need hystrix also along with feign client.

Exceptions:

Can you provide the complete stacktace? What do you mean it improved the connectivity issue?

  1. 我只有在启动时遇到类似的问题，并且总是遇到超时异常。
  2. 如果禁用，则仅下面的hystrix标志会在启动时正常运行。
feign:
  hystrix:
    enabled: true

hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds: 210000

但我们也需要假冒客户与hystrix。
