Invalid maximum heap size

[oscarvarto]

I can't "install" akka properly. Once I download Akka 2.0-RC4, I try
to run the sample microkernel application included in this download:


$ bin/akka sample.kernel.hello.HelloKernel

Invalid maximum heap size: -Xmx1024M -Xms1024M -Xss1M -
XX:MaxPermSize=256M -XX:+UseParallelGC -XX:OnOutOfMemoryError="kill -9
%p"
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Help!

Hi Oscar,

unfortunately you have given us 0 information to work with, like which OS, which jvm version etc.

have you've tried to google the error message? 

Cheers,

Thanks for the quick reply. Yes I've used google to solve this issue
by myself, and I haven't found anything useful.

I'm working on Arch Linux x86_64
$ uname -a
Linux compu4 3.2.8-1-ARCH #1 SMP PREEMPT Mon Feb 27 21:51:46 CET 2012
x86_64 AMD Phenom(tm) II X6 1055T Processor AuthenticAMD GNU/Linux
$ java -version
Picked up _JAVA_OPTIONS: -
Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel
java version "1.7.0_03"
Java(TM) SE Runtime Environment (build 1.7.0_03-b04)
Java HotSpot(TM) 64-Bit Server VM (build 22.1-b02, mixed mode)


I tried to use an environment variable:
export JVM_ARGS="-Xmx1024m -XX:MaxPermSize=256m"

it didn't work.

Hi

Invalid maximum heap size indicates there's something wrong with your -Xmx argument.  

I think your use of double quotes is confusing the JVM and it thinks -XX:MaxPermSize=256M is also part of the argument to -Xmx.

Try setting the environment variable to a value that doesn't contain double quotes.

e.g.  export JVM_ARGS='-Xmx1024M -XX:MaxPermSize=256M'

Cheers

Brian

A friend help me.

$ bin/akka sample.kernel.hello.HelloKernel
worked changing bin/akka according to the same file in version 1.3.1:

I removed this
