Clients are polling the config server

Not sure exactly what’s causing this, but my config server is getting hammered with requests from applications that are running and when I check the application logs I see multiple config fetches per minute, here’s one app’s log file for example:

2015-10-15 14:39:31.072  INFO 25849 --- [nio-8082-exec-6] c.c.c.ConfigServicePropertySourceLocator : Fetching config from server at: http://{config server host}:8888

Here’s what my bootstrap.yml looks like for all apps:

spring:
  application:
    name: {app name here}
  cloud:
    config:
      failFast: true
      uri: http://{config server host}:8888
      username: {removed}
      password: {removed}

I would expect the config clients to only request configs at startup and when /refresh is called. Is this a bug or have I missed some configuration option?

Looking at the code it seems when failFast is set a RetryOperationsInterceptor kicks in, but it should only retry 6 times by default. I am not familiar with how these interceptors work though, so this may or may not be related:
