okhttp3 memory high after stress test with http2

Question

Excuse me, I'm doing a stress test using http2 with okhttp3 as library I'm using JMeter as testing tool My thread is 200 for 300s and ramp up in 30s

I'm using docker as a platform After stress test, the memory goes up high into 8GB and never go down I already use code like this

> client.dispatcher().executorService().shutdown();
> client.connectionPool().evictAll();

And already using singleton for my okhttpclient

But still not go down Is there any things that I miss?

Thanks

Typically JVM programs never release memory until the process exits. It's a side effect of the way the memory is managed.
