-------------------------------

             Summary: mina sshd 1.6.0, using as sftp server, run for about one 
month, found that there is too many ConcurrentHaspMap  objects in Nio2Acceptor.
                 Key: SSHD-810
                 URL: https://issues.apache.org/jira/browse/SSHD-810
             Project: MINA SSHD
          Issue Type: Bug
    Affects Versions: 1.6.0
            Reporter: young_shaw
         Attachments: memleak2.png

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.
