Setup min 4GB heap memory for the server to process

Dear all,

I am facing this configuration issue when launching the as4 software.

I have tried editing the as4_start.sh file and manually setting more memory.
I have also downloaded the Java Dev Kit and tried editing the as4.jar file through the command line prompt with -Xmx4G.
Still the problem persists.

Could you please help?

Many thanks,

Paul
