This is happening because your default memory setting in Java Settings is too small for large medical images. You can change the setting as follows:

  1. Open the control panel for Windows.

  2. Locate and click the "Java" control panel icon.

  3. Within the Java control panel, select the "Java" tab.

  4. Click the "View" button within the "Java Runtime Settings" section.

  5. You should see a column named Java Runtime Parameters. In this field for your specific Java version enter the value "-Xmx512m" then click "OK".

You can confirm whether or not the change has been configured successfully by logging into CHILI/Web, clicking on Setup, selecting the "Memory" tab and looking at the value next to "Maximum memory available". If you've configured the value in step 5 above to "-Xmx512m", then you should see "Maximum memory available 508 MB".



On a Mac: Use "Finder" to get to: Applications -> Utilities -> Java and then, Choose your Java Version and click -> Options Then add the Memory setting "-Xmx512m" no quotes.  For additional performance enhancements choose the option to run Java in its own process (not in browser).
