Are there any memory restrictions when using Invoke-Command?

Question

Hi, I'm using the Invoke-PSCommandSample workbook to run a batch file inside a VM.
The batch file inside the VM runs a Java program.
The batch file works fine, when I run it manually in the VM.
However, when I use the Invoke-PSCommandSample workbook to run the batch file, I get the following error:
Error occurred during initialization of VM
Could not reserve enough space for object heap
errorlevel=1
Press any key to continue . . .
Does anybody know if there are any memory restrictions when invoking commands inside a VM via runbook?
Thanks in advance.

Hi Joe, I'll give some more background information. I'm doing load testing with JMeter in Azure and I want to automate the task. This is my runbook:
workflow Invoke-JMeter {
$Cmd = "& 'C:\Program Files (x86)\apache-jmeter-2.11\bin\jmeter-runbook.bat'"
$Cred = Get-AutomationPSCredential -Name "[email protected]"
Invoke-PSCommandSample -AzureSubscriptionName "mysubscription" -ServiceName "myservice" -VMName "mymachine" -VMCredentialName "myuser" -PSCommand $Cmd -AzureOrgIdCredential $Cred
This is my batch file inside the VM:
set JAVA_HOME=C:\Program Files\Java\jdk1.7.0_71
set PATH=%JAVA_HOME%\bin;%PATH%
%COMSPEC% /c "%~dp0jmeter.bat" -n -t build-web-test-plan.jmx -l build-web-test-plan.jtl -j build-web-test-plan.log
Initially I tried to run JMeter with "-Xms2048m -Xmx2048m". As that didn't work, I lowered the memory allocation but even with "-Xms128m -Xmx128m" it does not work. I have tried with local PowerShell ISE as you suggested, but I'm
running into certification issues. I'm currently have a look at this. Here's my local script:
Add-AzureAccount
Select-AzureSubscription -SubscriptionName "mysubscription"
$Uri = Get-AzureWinRMUri -ServiceName "myservice" -Name "mymachine"
$Credential = Get-Credential
$Cmd = "& 'C:\Program Files (x86)\apache-jmeter-2.11\bin\jmeter-runbook.bat'"
Invoke-command -ConnectionUri $Uri -credential $Credential -ScriptBlock {
Invoke-Expression $Args[0]
} -Args $Cmd
With this, I get the following error (sorry, it is in German):
[myservice.cloudapp.net] Beim Verbinden mit dem Remoteserver "myservice.cloudapp.net" ist folgender Fehler
