yesterday I added the Ext-Js 4.0 framework to my solution. Its a huge set of files and when I added it WebStorm started to index files. After a while I got an out of memory dialog letting my increase the mmmory size. I increased it in steps and restarted WS each time. When memory size reached 1.5G WS refused to start and showed me a warning that the allocated memory for the java-VM was to large and the the java VM couldnt be started.
