JVM can occupy the memory although they don't process any data.

But when the memory is full, the shuffle server pod restart,this case my spark application faild

[jerqi]

Why do the shuffle server restart? There should be some information in the logs or stdout.

[wfxxh]

It is restart by k8s, reason is memory is too high.I think if memory release ,it will not be appear

Maybe we should give more memory to the pod.

[wfxxh]

It is 32G now,I can not give more

[jerqi]

You can adjust the parameter of memory in the bin/rss-env.sh and conf/server.conf.

[wfxxh]

XMX_SIZE ? it is 30G now.

[jerqi]

XMX_SIZE ? it is 30G now.

Could you reduce the value?

[wfxxh]

I have reduced it to 8G，but the pod restart too

[jerqi]

I have reduced it to 8G，but the pod restart too

Does the server restart because of the same reason? You give the pod 32G memory, XMX_SIZE is 8G, don't it?
