Q: I sometimes get a "java heap space" error when running PDF Studio. What does this mean?
A: When running intense processes in PDF Studio, you may get a "java heap space" exception. This happens when PDF Studio is running out of memory. By default, PDF Studio is allocated 512Mb of memory. If your computer has 2GB of RAM or more, you can allocate more memory by following the steps below. Make sure you have enough memory available or your machine will start swapping and be unresponsive. On Windows: - Close / Exit PDF Studio
- Open the file called pdfstudio8.vmoptions located in PDF Studio installation directory: C:\Program Files\PDFStudio8
- Change -Xmx512m with -Xmx1024m
to increase the allocation to 1024MB, for instance
- Save the file
- Launch PDF Studio
On Mac: - Close / Exit PDF Studio
- Open Finder
- Go to Applications
- Right Click or CTRL + Click on the PDF Studio 8 Application icon and select "Show Package Contents" in the menu
- Click on Contents
- Double-Click on Info.plist
- (Lion Only) In Lion, the file is locked by default. Click on "Locked" and change it to "Unlocked".
- Open the Java "node" by clicking on the little arrow
- Change -Xmx512m with -Xmx1024m to increase the allocation to 1024MB, for instance
