Killing process in module 3

Trying to kill vsftpd processes using ‘sudo kill
process id’ but it’s not working…
Any suggestions?

ps -ef
then see process id of vsftpd
then force kill it by
sudo kill 9 <process_id>

Any clue to resolve this error

resolving this error is already there in forum, u have to create this directory yourself and include variable ‘secure_chroot_dir’
with the given directory path in .conf file
