Spring-cloud-netflix: Eureka client instances deregistering and closing Java processes

[angheladrianclaudiu]

Hi,

I have a microservice that is registering with eureka. And I am starting 4 instances of this microservice on 4 different ports. The thing is that after some time, all the instances are deregistering and are shutting down the Java processes. See below excerpts from the logs of the instances:

Instance 1:

The configuration that I am using in application.yml:

eureka:
  instance:
    prefer-ip-address: false
  client:
    registerWithEureka: true
    fetchRegistry: true
    serviceUrl:
      defaultZone: http://IP:port/eureka/
    healthcheck:
      enabled: true

Might now what the problem would be?

I am using Spring Boot 1.3.3.

Is it related to eureka.client.healtcheck.enabled? Could you check the response from /health endpoint?

[angheladrianclaudiu]

This is the response:

{"description":"Spring Cloud Eureka Discovery Client","status":"UP"}

Also, I had the same issue described above even before I set up eureka.client.healtcheck.enabled.

[ryanjbaxter]

What version of Spring Cloud are you using?

[angheladrianclaudiu]

Brixton.RC1

[ryanjbaxter]

Can you upgrade to Camden.SR7 or Dalston.SR3?

[angheladrianclaudiu]

I will give it a try. But will this help? Is there something in the framework that is called behind the scenes that is causing the deregistration from Eureka? I would also like to understand this.

[spencergibb]

Your using a very old release candidate that is no longer supported. Eureka went through many changes, so indeed, things may have fixed your issue.

[angheladrianclaudiu]

Ok. Thanks. I will give it a try soon and let you know.

I got the same problem. I resolved it by adding this dependency:

<dependency>
    <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-web</artifactId>
</dependency>

[girishgodage]

thanks dulipchandana . It works for me

org.springframework.boot
spring-boot-starter-web

[srinivasvadla]

Thank you.
