Why does StarTools crash in some demanding modules like SVDecon?

If you find StarTools sometimes crashes under heavy load in demanding modules like SVDecon, this may be due to your Operating System being incorrectly configured to provide enough virtual memory.

Ideally, you should configure your system to provide "unlimited" virtual memory. However, if this is not possible or desirable, a good rule of thumb is to make sure your operating system can provide at least 2x-3x the amount of physical memory as additional virtual memory (see tutorial for Windows, or install a package like SwapSpace on your Linux distro).
