 ## Limitations
 
 - The Eureka Server Java component comes with a default configuration, `eureka.server.enable-self-preservation`, set to `false`. This default configuration helps avoid times when instances aren't deleted after self-preservation is enabled. If instances are deleted too early, some requests might be directed to nonexistent instances. If you want to change this setting to `true`, you can overwrite it by setting your own configurations in the Java component.
