Could not reserve heap space

Question

I am using soap ui 5.0.0 open source. I am running soapui testcases through ant to get the Junit report

build.xml:

<project basedir="." default="testreport" name="FCMRestAPIAutomation">
<target name="SoapUI">  
    <exec dir="." executable="C:\Program Files (x86)\SmartBear\SoapUI-5.0.0\bin\testrunner.bat">
    <arg line="-r -j -o -f 'C:\Users\sn3020722\Desktop\Notification\New folder' -sFirstLoginTest 'C:\Users\sn3020722\Desktop\Notification\New folder\FCM Project.xml'"></arg>
</exec>
</target>
<target name="testreport" depends="SoapUI">
<junitreport todir="C:\Users\sn3020722\Desktop\Notification\New folder\API">
 <fileset dir="C:\Users\sn3020722\Desktop\Notification\New folder\API">
<include name="TEST-*.xml"/>
</fileset>
<report format="frames" todir="C:\Users\sn3020722\Desktop\Notification\New folder\reports\html">
 </report>
 </junitreport>
 </target>
</project>  

Error in the command prompt:

SoapUI:
     [exec] Error: Could not create the Java Virtual Machine.
     [exec] Error occurred during initialization of VMError: A fatal exception h
as occurred. Program will exit.
     [exec]
     [exec] Could not reserve enough space for object heap
     [exec] Result: 1

testreport:

I have added the following in the system environment variables.

_JAVA_OPTIONS: -Xmx2048MB

But still i am facing other issue that Soapui itself is not opened with the allotted space.. Any suggestion to workout the space issue..?

Answer 1

After downloading the SoapUI 5.0.0 package for windows, I found out that in the file testrunner.bat there is a configuration at line 31 :

set JAVA_OPTS=-Xms128m -Xmx1024m -Dsoapui.properties=soapui.properties "-Dsoapui.home=%SOAPUI_HOME%\"

As you can see, the maximum memory parameter is set to 1024m (-Xmx1024m). Can you change it in your file to 2048m and try again.
