Hmm, maybe it's because of the architecture? I'm on an AMD64 here.

This starts the server automatically:
$ ps xuaw | grep ftp
root 1771 0.0 0.0 104 28 ? Ss 09:08 0:00 runsv twoftpd
ftplog 1772 0.0 0.0 128 44 ? S 09:08 0:00 svlogd -t
/var/log/twoftpd
root 1773 0.0 0.0 6792 948 ? S 09:08 0:00 tcpsvd -v
-llocalhost 0 21 chpst -m3000000 -e./env twoftpd-auth cvm-unix twoftpd-xfer
alvherre 1778 0.0 0.0 5216 772 pts/9 R+ 09:08 0:00 grep ftp
Then I try to connect:
$ lftp -u alvherre localhost
Password:
lftp [EMAIL PROTECTED]:~> ls
`ls' at 0 [Sending commands...]
It sticks here and I see the CPU at 100% in a CPU monitor. This
line is replaced with the next one when I C-c:
Interrupted
lftp [EMAIL PROTECTED]:~> exit
On the "ls" command, I see the CPU pegged at 100%. When I exit lftp,
the CPU is still at 100%. The guilty process is twoftpd-auth:
$ ps u -C twoftpd-auth
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 1958 97.9 0.0 2660 380 ? R 09:13 1:08 twoftpd-auth
cvm-unix twoftpd-xfer

Yes. The configuration is the default, I think, and certainly the
startup script is. (It was started by "aptitude" or dpkg).
