I guess I'm on my own with this, so I'll document progress to the list 
in the hope
that someone else may find it useful.

In debug mode, I found this:

	FPing: probing 8 targets with step 300 s and offset 202 s.
	FPing: Executing /usr/local/sbin/fping -C 20 -q -B1 -i10 -r1
		followed by a list of only seven targets

The underlying cause turned out to be a file-access issue.  I run the 
SmokePing
daemon under its own user account, called 'smoke'.  This user also owns 
all the
data files for SmokePing.  The web server runs under a different user 
account,
'apache'.  The address registration file is maintained by the 
smokeping.cgi
script, triggered by the web server.

A first fix was to add the 'apache' user to the 'smoke' group, and to 
make the
directories in the data and htdocs group-writeable.

More work is needed to line up suexec and Perl's -T mode to do things 
'properly'.
