erlang

I have an Erlang application running as a daemon, configured as an SSH server. I can connect to it with an SSH client and I get the standard Erlang REPL.

If I 'q().' I shut down the Erlang VM, not the connection. If I close the connection ('~.' for OpenSSH, close the window in PuTTY) some processes remain under the sshd_sup/ssh_system_xx_sup tree. These appear to be stale shell processes.

I do not see any exported function in the shell module that would let me shut down the shell (and therefore the SSH connection) without affecting the entire VM.

How should I be logging out of the SSH session to not leave stale processes in the VM?
