I believe this is due to an optimization made in either 2.25 or 2.27
wherein a $Session would only get a Session_OnEnd event there was
something actually written to it. The problem is that the current
session garbage collector relies on session files on disk, but these
empty sessions have no files on disk associated with them, just
entries in the internal database.
As a temporary workaround, you could do this:
sub Session_OnStart {
$Session->{MARK} = 1;
}
This would create the session files on disk. I believe then
that Session_OnEnd events would fire as normal, and your
SessionCount would keep current. The performance penalty
of always writing to a $Session would be little more than
what was in 2.21.
I will fix this ASAP in my dev 2.29 version by reading in
sessions for garbage collection from the internal database
instead of files on disk, which will account for the prior
optimization. This is a change I need to make anyway for
the session garbage collector before creating a SQL db backed
implementation of $Session / $Application storage.
