Solving thread cleanup on paramiko

Question

I have an automated process using paramiko and have this error:

Exception in thread Thread-1 (most likely raised during interpreter 
shutdown)

....
....
<         


        

Answer 1

__del__ is not a deconstructor. It's called when you delete a object's last name, which doesn't nessesarily happen when you exit the interpreter.

Anything that manages a context, such as connections, is a context manager For example there is closing:

with closing(make_connection()) as conn:
    dostuff()

# conn.close() is called by the `with`

Anyways, this exception happens because you have a daemonic thread that is still trying to do it's work while the interpreter is already shutting down.

I think you can only fix this by writing code that stops all running threads before exiting.
