I have the same problem as yours, the :ssl spawns a lot process but not terminate them. The init calls are :ssl_gen_statem.init/1, :supervisor.tls_dyn_connection_sup/1, :tls_sender:init/1, the amount of processes of these calls are 1:1:1.
Not found the reason yet, so I wrote a task to monitor the process amount and restart the :ssl.
