@spencergibb @dsyer we are testing the performance of the eureka server. We just @EnableEurekaServer on the server instance. We have test it for about 20 hours with 1000 concurrence request and we found the memory of the eureka server is increasing gradually. it seems there will be memory leak.
the eureka server is running on PCF

PCF would have no impact
You could test locally and get more data
What version of spring cloud Netflix is it?

1.1.2
Dave Syer

Probably best to upgrade then. And get more data.

we also test it locally.
the latest release version is 1.1.5, is there any news?
all register and heartbeat information will store on memory?
Dave Syer

Yes
So you could easily design an automated test that looked like a memory leak but really it's just the registry growing.

the default heartbeat will be sent per 30s , right?
so the heartbeats will also cause memory growing?
Dave Syer

They shouldn't. There's no need for the data to accumulate if the clients are static.

do you means the clients will not send the heart beat if they are static?
Dave Syer
@dsyer
Sep 01 2016 09:44
No, I mean the server has no need to accumulate heartbeat data

is there any way to let eureka server set expired clients to DOWN instead of removing them?

Don't know
Not that we enable explicitly in spring cloud certainly

is it possible to override the following settings at deployment time? spring.cloud.deployer.yarn.app.streamcontainer.memory=,spring.cloud.deployer.yarn.app.streamcontainer.javaOpts=. Doesn't appear to work.

@markpollack, @sabbyanandan, or anyone familiar with s-c-df-server-yarn, is it possible to configure application resources on a per stream-app basis. Right now it seems that we can only set, say the memory configuration, across the entire stream via streamcontainer. We need to set javaOpts, memory, etc on per container basis. Is this possible?
