Description

For example, the instance of "org.apache.sshd.common.io.nio2.Nio2Acceptor" which adress is "0x732137c40" occupies 2,224,510,720 (71.65%) bytes.Its memory is mainly accumulated by the instance of "java.util.concurrent.ConcurrentHashMap$Node[]" "0x744a55fb8" loaded by the class "bootstrap class loader".

I am wondering where can I close and destory the Nio2Session. Please help me, thank you.
