Thanks Lester.

Now that was interesting.  My original line didn't have the $1 on the end 
of the match, so I added it.  Now I get "File Not Found" as a browser 
response and the trace doesn't show all those lstats.  Only one now and it 
is a stat (not lstat).

3156  12:41:52 stat("/httpd/iliffe", {st_mode=S_IFDIR|0755, st_size=4096, 
...}) = 0

Note that the requested script is no longer there.  It still gets the 
correct path from somewhere.  The log entries are:

ss -a shows socket 127.0.0.1:9015 is active:
tcp    LISTEN     0      128    127.0.0.1:9015                  *:*                    
tcp    LISTEN     0      0      127.0.0.1:9015                  *:* 

Any other ideas?  

FYI, buried in the php-fpm source code there are a number of comments about 
the problem of getting the correct directory path from Apache calls.  Looks 
like the PHP folks haven't solved the problem for PHP 7 yet.  While I was 
Googling this problem I noticed piles of reports of problems with nginx 
running php-fpm so maybe they resolved that first.  One other point is the 
big section in the man pages for lstat for Fedora 25 showing changes in the 
macros.  I'm not a good enough programmer to understand a lot of it.
