If you look through your logs you'll see entries like this:
Jun  6 11:54:30 pentagram inetd[327]: ftp/tcp server failing (looping),
service terminated

man inetd says you can change this by appending a number after the
wait/nowait entry in inetd.conf:

        The optional ``max'' suffix (separated from ``wait'' or ``nowait'' by a
        dot) specifies the maximum number of server instances that may be
        spawned from inetd within an interval of 60 seconds. When omitted,
        ``max'' defaults to 40.

Just kill -1 inetd to reenable.

I think ssh getting slow was just ssh getting slow (from all the daemons
being forked).
