Description:
Logging in via inetutils (ftp command) with local user on vsftpd works just fine... until I type ls: 421 Service not available, remote server has closed connection
And then I found this on my journalctl -xe:

mar 15 12:03:35 myghistation systemd-coredump[1858]: [🡕] Process 1846 (vsftpd) of user 65534 dumped core.
