URL: https://github.com/apache/mina-sshd/issues/506
### Version
2.12.1
### Bug description
Those code below is my demo code. It works fine on local enviroment. But it
does not work after deployed to remote server. The log output is shown below.
But oddly, after restart the server, it works with no exceptions. And a
period later（ussally after when another user logged in and try to upload file
to sftp with this）, it does not work with error log outputted again.
Enviroment:
jdk 1.8
resin 4.0.66
Ubuntu 24.04 LTS
```
public void connect() throws IOException {
// Security.removeProvider("BC");
SshClient client = SshClient.setUpDefaultClient();
FileKeyPairProvider keyPairProvider = new
FileKeyPairProvider(Paths.get(privateKeyPath));
client.setKeyIdentityProvider(keyPairProvider);
client.start();
System.out.println("add key to session only with try");
ClientSession session =
client.connect(login,server,port).verify().getSession();
session.auth().verify();
// session.setKeyIdentityProvider(keyPairProvider);
this.session = session;
this.client = client;
}
public void uploadFile(String sourceFile, String destinationFile) throws
IOException {
try {
SftpClient sftpClient =
SftpClientFactory.instance().createSftpClient(session);
File tmpFile = new File(sourceFile);
String fileName = tmpFile.getName();
String destinationFilePath = destinationFile.endsWith("/") ?
destinationFile + fileName : destinationFile + "/" + fileName;
SftpClient.Handle handle = sftpClient.open(destinationFilePath,
EnumSet.of(SftpClient.OpenMode.Write, SftpClient.OpenMode.Create));
String fileData = new
String(Files.readAllBytes(Paths.get(sourceFile)));;
sftpClient.write(handle, 0, fileData.getBytes(), 0,
fileData.length());
sftpClient.close(handle);
sftpClient.close();
if(session.isOpen()){
session.close(true);
}
if(client.isOpen()){
client.close();
}
} catch (IOException e) {
throw e;
}
}
```
And after every transfer task, I disconnect as below:
```
public void disconnect() throws IOException {
if (c != null) {
c.disconnect();
}
if (channel != null) {
channel.disconnect();
}
if (session != null) {
session.disconnect(0,"");
session.close(true);
session = null;
}
if(client != null) {
client.stop();
client.close();
client = null;
}
}
```
### Actual behavior
not function well
### Expected behavior
