I keep receiving a bug that states: "java.lang.OutOfMemoryError: Java heap space." What does this mean?

On a Macintosh:

  1. Right click on the AT application and select show contents
  2. In the contents folder open info.plist (this should launch the Property list editor)
  3. Open root -> java -> VMOptions
  4. Change -Xmx256M to either -Xmx512M or -Xmx1G depending on how much memory you want to allocate

On Windows XP (this should be the same for Vista)

  1. Open the Archivists Toolkit lax file in your favorite text editor
  2. Find the following line:

    lax.nl.java.option.java.heap.size.max=

  1. Change the value which is expressed in bytes

    256M = 268435456

    512M = 536870912

    1G = 1073741824
