About every 3 or 4 days, my ProFTPD service stops accepting
connections with the following message:
[root@mars proftpd]# ftp localhost
Connected to localhost (127.0.0.1).
220 FTP Server ready.
Name (localhost:root): jdoe
500 not understood
Login failed.
ftp>
I keep on having to restart the service to get it going. Here is the output in debug mode:
