Hi Sean,
I have tested Performance of function fileexists(). This function is not not a
bottleneck. Also in a directory it doesn't search inside other folders.
Following scenario i used to test this:
30 Vusers for 10 mins trying to hit some randomly generated filenames(some of
them do not
This may not be directly related. When you use CF server monitoring, can you
disable the memory tracking option and check if that helps?
Thanks,

Hey everyone,
An update:
* We installed FusionReactor
* Deployed the site on a development box running CF Enterprise
* Ran a number of load tests and tests on discrete parts of the application
* Did various application and memory monitoring using both FusionReactor and
CF's Server Monitor

Moreover, in the CF Server Monitor it shows that CF is
actually destroying the objects as expected and releasing
memory back into the pool. However, if you actually look at
Jrun in the Task Manager, it's not. And, hitting Run GC to
invoke garbage collection in the Server Monitor doesn't
We had a similiar issue. Let me preface by saying I have not read this entire
thread so if the info I give is redundant.. sorry.
Anyways, we had a similiar issue. Code that worked fine under CFMX 7 would
cause Jrun cfmx 8 to suck down memory until it crashed. We narrowed it down

CF8 ships with JDK 1.6
Version 1.6_06 isn't supported by CF8; 1.6_04 is the latest version
showing in the support matrix. Regardless, 1.6_06 still suffers the
classloader issue (which isn't fixed until 1.6u10 and that's still in
beta).

Isaac,
That's an interesting guess and comment. We should test it and see if it
does degrade performance as you suggest.
Sean,
I would try the JVM arguments the other guy suggested first tho... I
really wouldn't put what I mentioned high on my list of likely suspects.
But thanks for the
Thanks everyone for all your suggestions. Some initial JVM tweaking didn't
solve anything, but you've given me a number of things to follow up on. Will
let you know how it goes.
Cheers,

1. Get a staging server (I see you have one)
2. Setup some load testing software, and setup a test that can reproduce the
leak (I see you can do that too)
3. View the staging server under load, and review it under
SeeFusion/FusionReactor/Server Monitor, and see if you can see where the
memory is
Hey Sean,
I know you said you already did a thorough code review and fixed all the
errors so you're not having any application errors, however, my guess
would be there's still some kind of subtle recursion-related issue
that's been overlooked. I would be real surprised if fileexists() does
Sean,
It looks like your jvm.config may need some tweaking.
Try these settings
java.args=
-server
-Xmx1024m
-Xms1024m
-Dsun.io.useCanonCaches=false
-XX:MaxPermSize=256m
-XX:PermSize=256m
-Dsun.rmi.dgc.client.gcInterval=60
-Dsun.rmi.dgc.server.gcInterval=60
-XX:+UseParallelGC
It is key
