It doesn't appear to hamper any functionality that I've tested, but puts Dev Ops on the edge. Using Spring Cloud parent Brixton.RELEASE, Spring Cloud 1.1.0.RELEASE and Spring Boot 1.3.5.RELEASE.

Duplicate with #1055. Could you provide a simple project reproducing this error ?

[haraldsk]

This is also confirmed in Spring Boot 1.4.0.

[bobkilla]

It may be a duplicate of #1055 but this issue has been locked and no progress has been made since then. Do you have more info about it? ping @spencergibb (since you locked the other issue). Thanks

[spencergibb]

@bobkilla log an issue upstream? or comment on this one https://github.com/Netflix/eureka/issues/907

Dalston uses eureka 1.6.2 which may help, but I don't see anything we can do.

[lferna]

I have the same problem as #1060 and #1055. Last one is locked, so the problem continues.

[dsyer]

I have unlocked the conversation at #1055 (the duplicate issue). There's still nothing there that says to me that a) there is a problem we can fix here, or b) if there is how to reproduce it. So please don't bother to comment unless you can move one of those things forward.

[lferna]

Thanks @dsyer , I'll put in #1055 how to reproduce the problem.

I observed if i set eureka.client.enabled=true in my config server and
hit http://localhost:8888/monitor?path=application
i get the following response

@mradulpandey posting the same content to multiple issues from different GitHub accounts is not helpful, please don't so this.

[asarkar]

Reported mradulpandey for abusing GitHub T&C.

[spencergibb]

That's a bit harsh
