How many memory that your machine has? I set the memory by changing the jmeter.bat.
Somebody said that it can be done via set system.properties. But I don't know how. -----Original Message----- From: Samaraweera, Ravinda [mailto:[email protected]] Sent: Tuesday, August 28, 2012 4:46 PM To: JMeter Users List Subject: RE: OutOfMemoryError: Java heap space Is there any other place to change heap value other than jmeter.bat file? Coz when I change it , set HEAP=-Xms512m -Xmx512m to set HEAP=-Xms1560m -Xmx1560m it gives an error, I can run jmeter.bat file even, it exits Why is that? -----Original Message----- From: Jim (Jiemin) Jin [mailto:[email protected]] Sent: Tuesday, August 28, 2012 12:52 PM To: JMeter Users List Subject: RE: OutOfMemoryError: Java heap space With heap size set to 1560M, it can support about 500 users.

Keep the test plan simple, do not add too many unwanted listners as this would take away lot of memory locally during run time. Increase this heap size from systems.properties file , there is already a lot of ans posted on how to do this via jmeter forums. If the above doesn't solve your problem due to extensive load test harness, you can give a try using distributed load testing process.

Why? could be a number of reasons... the first being that you simply didn't configure enough to run your tests. JMeter heap usage will not stabilize because during a run JMeter accumulates results. If you have a long run you'd better use a very large heap. -- Kirk On 2012-08-28, at 8:08 AM, "Samaraweera, Ravinda" <[email protected]> wrote: > Dear All, > > What is the cause for following error? > > 2012/08/28 12:27:47 ERROR - jmeter.threads.JMeterThread: Test failed! > java.lang.OutOfMemoryError: Java heap space > > Thanks, > Chi. > > ********************************************************************** > * > Disclaimer > > The information contained in this communication is confidential and may be legally privileged. > It is intended solely for the use of the individual or entity to whom it is addressed and others authorised to receive it. > If you are not the intended recipient you are hereby notified that any > disclosure, copying, distribution or taking action in reliance of the contents of this information is strictly prohibited and may be unlawful. > KPMG is neither liable for the proper, complete transmission of the > information contained in this communication nor any delay in its receipt. > ********************************************************************** > * > --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected] Information contained and transmitted by this e-mail is confidential and proprietary to iGATE and its affiliates and is intended for use only by the recipient.
