What feature(s) aren't working right?
SSH
What version(s) of paramiko are you using?
3.3.1
What version(s) of Python are you using?
3.10.13
What operating system and version are you using?

If you're connecting as a client, which SSH server are you connecting to?
No response
If you're using paramiko as part of another tool, which tool/version?
No response
What are you trying to do with paramiko?
We have a test automation framework which uses paramiko as the underlying library for ssh connections to the cisco product. We have the framework running multiprocess env and it occurs intermittently and hangs.
We use atfork() to close the transport channel whenever we fork a new child process because the existing connection could be used by the parent process.
Here 148 is the cisco box and connecting from RHEL 82 where our tests are being run using paramiko ssh.
Can you please let me know is there a mutex lock or somewhere thats not cleaned up. How do we debug this further?
Regards Sai
How are you trying to do it, and what's happening instead?
