The remote WarFTPd server is running a 1.71 version.

It is possible for a remote user to cause a denial of
service on a host running Serv-U FTP Server, G6 FTP Server
or WarFTPd Server. Repeatedly submitting an 'a:/' GET or
RETR request, appended with arbitrary data,
will cause the CPU usage to spike to 100%.

Solution : upgrade to the latest version of WarFTPd
