Hmmm after the last dialog screen I got an error while trying to finish ispCP installation:

--------- IMPORTANT INFORMATION FOR XINETD USERS ----------
The following line will be added to your /etc/inetd.conf file:

ftp stream tcp nowait root /usr/sbin/tcpd /usr/sbin/proftpd

If you are indeed using xinetd, you will have to convert the
above into /etc/xinetd.conf format, and add it manually. See
/usr/share/doc/xinetd/README.Debian for more information.

What's the cause? Out of memory? How do I best fix this?
