I've got that one sorted, deleted the logfile and restarted vsftpd.

Now got other problems:

Need anonymous ftp, configured ftpd correct (I think).
Created a user "ftpuser" for anoymous ftp in /var
ls -Z looks like this:

drwxrwsrwx  ftpuser  ftpuser  system_u:object_r:ftpd_anon_t    ftp

In ftp I have
drwxrwsrwx  ftpuser  ftpuser  system_u:object_r:ftpd_anon_t    pub

And get 553 errors, 

TYPE I
200 Switching to Binary mode.
PORT 192,168,0,2,6,45
200 PORT command successful. Consider using PASV.
STOR 465_v6.pdf
553 Could not create file.
Transfer request completed with status: Failed, 1 SubItem(s) failed


The audit log look like this
