JMeter goes Out of Memory
Hi,
We are using JMeter for Performance testing of one of the critical
application. We are using JMeter for testing Web service calls.
When we execute the test with 4 users, the Jmeter goes out of memory and
we can not proceed with the test runs.
We are not using any memory intensive listeners in out test plan. We are
using simple data writer.
The configurations in our Jmeter.bat files are as follows:
rem See the unix startup file for the rationale of the following
parameters,
rem including some tuning recommendations
set HEAP=-Xms512m -Xmx512m
set NEW=-XX:NewSize=128m -XX:MaxNewSize=128m
set SURVIVOR=-XX:SurvivorRatio=8 -XX:TargetSurvivorRatio=50%
set TENURING=-XX:MaxTenuringThreshold=2
set EVACUATION=-XX:MaxLiveObjectEvacuationRatio=40%
set RMIGC=-Dsun.rmi.dgc.client.gcInterval=600000
-Dsun.rmi.dgc.server.gcInterval=600000
set PERM=-XX:PermSize=256m -XX:MaxPermSize=256m
set DEBUG=-verbose:gc -XX:+PrintTenuringDistribution
JMeter machine configuration:
32 bit processor and 1.88GHz , 2 CPU and 4GB RAM
Application server configuration:
64 bit processor, 2 CPU and 8GB RAM
We also tried changing the heap size to 1024m but, after that when we
run the Jmeter we get the error as JVM could not be initialized.
Please suggest how we can solve this problem.
Regards,
Ragini Thakur

It will be good if you will use java profiler for identify which
objects are used 512m from JVM Heap. Maybe memory leaks?
How many threads you can start with the following HEAP settings?
-Xms128m -Xmx128m

I don't know why you need odd threads. All suggestions is not good as
for me. I think it is needed to fix OutOfMemory issue.
So:
1. You can use 3 JMeter servers :). Even on one machine.
2. You can add special parameter on the server for correct thread
numbers. For example, jmeter-server.bat -Jloop.offset=0.
3. You can use some flag (user parameters) for interrupting excess threads.
4. etc...
But I think it is another thread for discussion.

Hi,
I am not sure if JaVa Request is the cause of error. JMeter exceeds heap

To resolve this issue we are not using Distributed testing in this there
are 2 Jmeter servers. But now we are facing issue of distribution of odd
no of threads across tests. This is because when we configure the no of

Are you sure that is not the cause of the problem?
JMeter can normally handle many more than 4 threads.
For example on my 1GB system I'm currently running a 200 thread Java
Request test which is generating over 2000 samples/second. Admittedly
the is no IO involved. A test using the HTTP sampler against a local
Tomcat shows similar capablilities (200 threads, over 2000
samples/second) on the same system.

RE: Re[2]: JMeter goes Out of Memory
Posted by Ragini Thakur <ra...@cybage.com>.
Hi,
We are using JMeter 2.3.0 and java 1.5. We are not using any assertions
or pre or post processors.
Also we are not using the SOAP request sampler. It did not matched with
our performance testing requirement, so we have customized the Java
request sampler to invoke web service request.
Regards,
Ragini Thakur

Which version of JMeter ? Java?
And which samplers do you use?
Do you use lots of Assertions, Pre or Post-Processors?

Hi Dmitry,
We are using Linux OS for the application server and Windows for JMeter.
We are getting jav.lang.OutOfMemory error. Our JMeter machine is 32 bit
processor with 4GB RAM.
