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 exis
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,
Hemant

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).

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

Whoops, somehow submitted that post twice. Sorry for the double-posting...

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

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,

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 fo

Sean,
It looks like your jvm.config may need some tweaking.
Try these settings

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
