I think those are very good points J.
For starters, yes we are using Reactor in the application scope. We also
use something I have blogged about (and was subsequently schooled on) using
a factory to produce Reactor gateway
instances<http://daveshuck.instantspot.com/blog/index.cfm/2006/11/9/Factory-example-using-our-Reactor-Gateway-Factory>.
There were two arguments against that technique, those being a) Reactor may
handle this on its own anyway and b) Isn't this a job for ColdSpring? That
said, we still have this in place so it is worth noting.
Additionally, we have almost completely gone away from using the objects on
the public sites in favor of outputting from the Reator query objects. We
didn't find any notable memory issues with using the objects, but we found
considerable performance problems with our approach. (more
here<http://daveshuck.instantspot.com/blog/index.cfm/2006/10/6/Lessons-learned-using-Reactor>...).
Again, that problem may *very* well be a usage problem rather than a
framework problem, but it was what we experienced regardless.
Within the user administration section we make much heavier use of the
Record objects, with the exception of when we have to manage large
recordsets.

The whole discussion of Reactor and memory leaks started nearly 6 months
ago and it's cropped up several times with people saying "I have reactor in
one version of the site and not in the other and the one with Reactor blows
up every {6 to 48} hours." I'm starting to think this is a function of usage
and/or developer "error" (error in the sense that the dev is doing something
that's not quite kosher and different than the plenty of people who DON'T
have this issue). I'm not coming down on anyone, but I think we might want
to switch this conversation from "Reactor is causing memory leaks" to
"what's different between those that have the issue and those that don't
have the issue?"
Even Doug was having issues with ReactorBlog and a memory leak that would
down his instance every n-hours... so Dave, how are you using Reactor and
it's generated objects? Are you using Records as "beans" and passing them
around? Are you using the TOs instead?
Do you keep ReactorFactory in the application scope?
I think we should be focusing on finding the differences between one
implementation that bombs and one that doesn't...
Anyone?

Our memory has stayed on a completely flat line since we launched it in
early September, with only slight increases during heavy traffic times as we
expected, but is subsequently released as it should.�� We have only
restarted the server once and it was due to an unrelated ColdFusion issue
regarding mail queues.�
