Start Jboss

Hi,

I try to make the installation of livecycle Es v8.0 on a windows server 2003 SP1 R2 2.4 GHZ with 4G of ram.

I installed the sun sdk version 1.5.0.16 on my system.
I installed the preconfigure adobe Jboss server.

when I try to start Jboss on command line : run.bat -C
I have the following error :

Error occurred during the initialization of VM
Could not reserve enough space for object heap
Could not create the Java Virtual Machine.

The option in the run.bat file are :
MaxpermSize = 256m -Xms : 256m -Xmx : 1024m

I try with :
MaxpermSize = 1024m -Xms256m -Xmx1024m
and
MaxpermSize = 256m -Xms256m -Xmx2048m

It works with 32m 32m 32m but is it enough to works LC fine ?

Could you help me ?

Thanks you
