java.lang.OutOfMemoryError
I've noticed the Jmeter 1.7 series has a pretty bad memory leak. It's
noticable in both the release (1.7) and the nightly builds up to and
including August 1. I haven't checked any other builds, but I would suspect
the same.
The memory leaks are apparent in JMeter running on Linux using Sun's 1.4.0
JDK.
Also, I run into a java.lang.OutOfMemoryError throwable when attempting to
load a 29MB jmx file. Is there a particular reason why Jmeter needs to load
the entire file into memory? At least...that's what I'm assuming is causing
this problem.
I've got a jmx script that will create 1000 users on my system. I want to
load test my server under this environment. I suppose if I can't use Jmeter
to do it, I'll have to write my own code. I just thought it'd be easier to
use a package that was already written.
Thanks for any help.

This is not a memory leak - it is simply very great memory usage. The tree listener is not
intended to be used is such large tests because it saves all results for viewing.

Hi All,
I noticed a leak as well that disappeared (or at least was greatly reduced)
when I removed the "tree" listener.
I was asking for the same, rather large "page" over and over.
Reliably ran out of memory after 870-900 requests.
Mac OS X.1.5 and CVS top of tree from about 9/5/02
Sorry, I don't have the Java runtime version handy.

I'd suggest changing your bash script to generate a users.xml file for the User Parameter
Modifier to use instead. Then, use a loop controller to loop through the add sample, and let
the User Parameter Modifier plug in the unique data.
Or, you could use your bash script to run JMeter in non-gui mode, and run it 1000 times,
changing the test script slightly between each run.

My script grabs all the images, javascript and stylesheets for the pages used.
The middle section performs a web page operation to add some data to the
database. It processes 1000 add operations. It cannot be accomplished with
loop controller, as it needs to be unique data. So, I generated the jmx file
using a bash script, and then tried to load it up in jmeter.

Forgot to answer this...sorry.
Yes, I have tried increasing the size of the java heap. Both the initial and
the maximum sizes.

Have you tried increasing the memory available to the JVM? And why would you
need a jmx file that's 29MB?
