Eureka Client не может отправить биение

2 голосов
/ 26 марта 2019

У меня появляются спорадические журналы, которые говорят мне, что клиент Eureka не может отправить свое сердцебиение на сервер Eureka. Регистрация работает нормально, и она может отправить 95% его пульса. Я вижу спорадические сбойные вызовы только в тех случаях, когда они не запускаются на той же виртуальной машине, что и eureka.

Мы обновили загрузку Spring до версии 2.1.2 и использовали бомбу с Greenwich.RELEASE (до того, как мы использовали Finchley.RELEASE). С Finchley.RELEASE мы видели эти журналы очень редко, если таковые имеются.

Конфиг клиента в application.yml 

eureka:
  instance:
    prefer-ip-address: true
    ip-address: ${HOSTNAME}
  client:
    serviceUrl:
      defaultZone: http://my-eureka:8761/eureka/

Если я выведу зависимости gradle, я увижу, что http-клиент был обновлен до последней версии исправления: 4.5.7
