### description I wrote an sftp server proxy using mina-sshd, and I found that the listener logging for open requests took a long time to process, sometimes blocking. ### Log Description One of my test logs showed a difference of about 20s.See attached sftp-2160-test-ls.log for the full log `2025-11-25 18:38:37.859 [sshd-SshClient[6c827e56]-nio2-thread-1] TRACE org.apache.sshd.common.io.nio2.Nio2Session - handleCompletedWriteCycle(Nio2Session[local=/0:0:0:0:0:0:0:0:53369, remote=/10.10.16.195:1234]) finished writing len=80 at cycle=18 after 536100 nanos 2025-11-25 18:38:52.862 [sshd-MySftpSubsystem-58008-thread-1] DEBUG org.example.sftpServerTest.SftpAuditRecorder - TEST LOG: Open file: /` ### Some information Appears when the target device is a network device. In 2.16.0, it doesn't block when I comment out the log output in the open method of SftpAuditRecorder. In 2.13.2, log printing blocks even if you comment it out. ### attachment [sshd-sftp-2160-Test.zip](https://github.com/user-attachments/files/23744854/sshd-sftp-2160-Test.zip) [sftp-2160-test-ls.log](https://github.com/user-attachments/files/23744856/sftp-2160-test-ls.log) -- This is an automated message from the Apache Git Service.
