---------------------------------
Summary: org.apache.sshd.common.io.nio2.Nio2Acceptor#bind failed
cause file descriptor leak
Key: SSHD-877
URL: https://issues.apache.org/jira/browse/SSHD-877
Project: MINA SSHD
Issue Type: Bug
Affects Versions: 1.7.0
Environment: java: 1.8
os: centos7
ssh client: xshell 5
Reporter: Zhenliang Su
Attachments: Main.java, nio2acceptor.png
When the binding fails in org.apache.sshd.common.io.nio2.Nio2Acceptor#bind, the
file descriptor will be leaked.
Possible reasons:
When AsynchronousServerSocketChannel#bind bind a port that has already been
listened to, the code will throw a BindException, but the code does not handle
the exception, causing the socket to have no chance to be turned off.
Eventually results in a limit on the number of maximum file descriptors that
exceed the system.
Compile Main.java and run it on a linux machine.
Use the client to connect to the server and the client to set up x11
forwarding. Using lsof on the machine where the server is located, you can see
the file descriptors that have not been released.
