How to eliminate the "Eureka may be incorrectly claiming instances are up when they're not" warning on Eureka Dashboard?

Question

How to eliminate the following message on Eureka server dashboard? Will it cause any issue to my services?

EMERGENCY! EUREKA MAY BE INCORRECTLY CLAIMING INSTANCES ARE UP WHEN THEY'RE NOT. RENEWALS ARE LESSER THAN THRESHOLD AND HENCE THE INSTANCES ARE NOT BEING EXPIRED JUST TO BE SAFE.

Thanks.

Answer 1

Sample Disable this warning: add this property on application.properties file

 eureka.renewalPercentThreshold=0.85

OR

 eureka.server.enableSelfPreservation=false

But enableSelfPreservation also shows another warning message that you disable it.

Answer 2

On your EurekaServer configuration properties file, change the value of wait-time-in-ms-when-sync-empty to zero or delete this line, cause default value is zero.

eureka:
  server:
    wait-time-in-ms-when-sync-empty: 0
