When running project from IntelliJ IDEA I set VM options -XX:MaxPermSize=512m -Xmx=256m -Xms=256m and get the following error
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Invalid maximum heap size: -Xmx=256m
Remove the equals sign after Xmx and Xms.
Correct VM options: -XX:MaxPermSize=512m -Xmx256m -Xms256m.

I'm trying to create a minecraft server and the following error:
E:\Documentos\Minecraft>java -Xms1G -Xmx2G -jar server.jar -o false
Error occurred during initialization of VM Could not reserve enough
space for 2097152KB object heap E:\Documentos\Minecraft>PAUSE
Pressione qualquer tecla para continuar. . .
Can someone help me?
Your error message states
"Error occurred during initialization of VM Could not reserve enough space for 2097152KB object heap"
You don't have enough memory to run your server. Try upgrading your storage capacity.
The computer you are running this on does not have enough memory to allocate 1 gigabyte to a process. You will need to get a computer with more RAM to run a server.
You are using more RAM to the server that you have, in run.bat change:
java -Xms1G -Xmx2G -jar server.jar -o false
to
java -Xms1G -Xmx1G -jar server.jar
In recent versions "-o" don't works more.
Currently we are encountering an problem, our java application can run smoothly with JRE6, but for JRE7, it will report "Could not create the Java virtual machine" sometimes and failed to start program. we have "-Xmx1024m" option in the launch command line.
after searching in google, people suggest check the max heap size that can be requested in PC. then I tried below ones.
for JRE6,
C:\Users\joey>java -Xmx1214m -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) Client VM (build 20.45-b01, mixed mode)
C:\Users\joey>java -Xmx1215m -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
for JRE7,
D:\Program Files\Java\jre7\bin>java.exe -Xmx930m -version
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) Client VM (build 24.51-b03, mixed mode)
D:\Program Files\Java\jre7\bin>java.exe -Xmx931m -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
And when i close most processes in PC and free memory to 2.5 GB, for JRE7, it will succeed with 1094m, like below.
D:\Program Files\Java\jre7\bin>java.exe -Xmx1094m -version
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) Client VM (build 24.51-b03, mixed mode)
D:\Program Files\Java\jre7\bin>java.exe -Xmx1095m -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
It seems that the max heap size that JVM can request is related with system available memory size, does someone know the exact relationship?
Is there some way to enable tracing logs of JRE when creating JVM?
Thank you!
Regards,
Joey
I faced the same issue on various Windows OS flavous (Win7, Win2008R2) while having enough free RAM (3-5G), when switching from jre6_20 to jre7_51 (both 32 bit VMs)
Using vm args -Xmx1300m and -XX:MaxPermSize=256m on java 6 the VM is able to start. However, with java7 I had to lower down startup max memory (xmx with 100m or permgen with 100m) in order to be able to start VM.
The interesting part is this: if I restarted my box, the jvm 7 started with original vm args (-Xmx1300m and -XX:MaxPermSize=256m) so I suspect the root cause might be the OS with JVM combination.
I know that on Windows OSes - 32 bit VMs expect to have a single large chunk of memory, but cannot use the maximum process memory size will range from 1.4G to 1.6G (because of additional constraints)
Any troubleshooting pointers? Oracle does not provide any information in java7 release notes (or I could not spot those)
I have a similar problem Windows 7 64bit, no JAVA_HOME set nor in PATH
This fails

This works

This also works (I can recompile or not, doesn't make a difference
"C:\Program Files (x86)\Java\jdk1.6.0_45\bin\java.exe" -Xms32m -Xmx1024m -XX:MaxPermSize=256m -version
I tried turning off windows DEP, didnt make a difference

I twiddled with the Virtual Memory settings , changed from allowing Windows to Manage
http://windows.microsoft.com/en-us/windows/change-virtual-memory-size#1TC=windows-7
I upped the Virual Memory in windows and it allowed it to work, sometimes...(with xmx1024)
Nothing else is consuming a lot of resources (memory, etc, I did have oracle database running locally, but shut it down)

Have you defined AXIS2_HOME environment variable ? If so remove that and try. You can see that
Using AXIS2_HOME: D:\axis2
is not using some other server. (I tried to start server in windows and started successfully.)
In Linux you can do this
Go to home folder
press Ctrl + h (to show hidden file)
Open .bashrc file
If $AXIS2_HOME is defined remove it and then add
export AXIS2_HOME=""
export PATH=$PATH:$AXIS2_HOME
This will remove even if you downloaded Axis2 from apt-get
I want to increase the heap size of my Glassfish. For that, I know that I can go up to 4GB:
java -Xmx4000M -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03-384-10M3425)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-384, mixed mode)
I tried to set in domain.xml file the -Xmx to 2GB:
<jvm-options>-Xmx2000m</jvm-options>
But I am getting the following error:
asadmin> start-domain
Waiting for ... to start .Error starting domain ...
The server exited prematurely with exit code 1.
Before it died, it produced the following output:
Error occurred during initialization of VM
The size of the object heap + VM data exceeds the maximum representable size
launchctl bsexec failed: Inappropriate ioctl for device
Launching the command with -v option gives this:

Command start-domain failed.
I found the problem. For some reasons which I do not understand, the "-d32" argument was passed in the command, asking to start in 32 bits mode. When adding
<jvm-options>-d64</jvm-options>
to the domain.xml file, glassfish starts. Please note that this option is not present by default in the file.
you must be using a different Java install when doing the "-version" and from within GlassFish. I can reproduce the same error with the default "java" in Mac OS' path but not when using an absolute path :
% /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java -Xmx2300m -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03-383-11A511)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-383, mixed mode)
% java -Xmx2300m -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
Could it be that you don't have enough disk space on your system? Reserving 4GB of RAM may require MAC OS to expand swap space, and you may not have the disk space to do this. Unfortunately, this has burned me before :-/
I am getting following error message all of the sudden. 5 minuted before everything was working fine.

Have you tried increasing the Java VM maximum memory allocation ? e.g.
java -Xmx512m ...
will set the maximum memory allocation to 512m. You may be running with the default memory settings, and that may not be sufficient for your application. See here for an introduction to the available options and what they mean.
