ftasv and ScoreBoardFile on FreeBSD 10 with jails

We recently upgraded some FreeBSD 9.1 servers to FreeBSD 10.1 and found
it broke the scoreboard viewing utility we were using, the "ftasv" port.
For that tool to work apache is supposed to be configured to use 'a
"name based" shared memory segment' (from their README) by the directive
That used to (on 9.1) create that "file". Then we could execute 'ftasv
/var/run/apache_status' to interpret that file, and see what requests
apache was working to serve.
This even worked with many different apache instances running each in
their own jail, where all the jails actually share the same basejail
/usr/local/sbin/httpd binary. Inside each jail we could see just the
requests that instance of apache was working on.
But after the FreeBSD upgrade to 10.1 we no longer see the apache_status
file in the filesystem, and ftasv seems to actually report the most
recent hits from the most recently restarted instance of apache, even if
that's in another jail!? (On a system with no jails, it's not a problem,
so I suppose I'll cross post to the freebsd-virtualization list too. .
Has anybody else seen this behavior?
