Ok I've managed to find the file which controls the heap space which Flex Builder allows called the FlexBuilder.ini file in Computer/C/ProgramFiles(86)/Adobe/Flex Builder 3/ but the problem is I can't raise the xms and xmx attributes above 512 as when I try to start Flex I get the message "Unable to load the java virtual machine" and then a window comes up with a message of "JVM terminted. Exit code=1"
But if I leave both values at 512 it works fine but I get an out of memory error whenever I run a big application I've made. This is why I wanted to increase them to 1024 like I have done with the perm sizes to solve this out of memory error. Does anyone know why this is happening? My system is quite new and has 2gb of RAM. The contents of my flexbuilder.ini file are:- -vmargs -Xms512m -Xmx512m -XX:MaxPermSize=1024m -XX:PermSize=1024m -Djava.net.preferIPv4Stack=true
