All postscript errors that you may seen on screen are not generated by AccuRIP, rather the OS and PS engine. It simple means there is an issue that will not allow the code t pass through the engine. Basically it fails to pass all checks points. When it comes to graphics, it is usually a bad font, over traced art with thousands of anchor points, etc. The best thing to do is RASTERIZE (bitmap) the entire file nd send it again.
For other uses, see Stack overflow (disambiguation).
In software, a stack overflow occurs when too much memory is used on the call stack. The call stack contains a limited amount of memory, often determined at the start of the program. The size of the call stack depends on many factors, including the programming language, machine architecture, multi-threading, and amount of available memory. When a program attempts to use more space than is available on the call stack (that is, when it attempts to access memory beyond the call stack's bounds, which is essentially a buffer overflow), the stack is said to overflow, typically resulting in a program crash. This class of software bug is usually caused by one of two types of programming errors.
There are thousands of codes. The most common is "limitcheck". Basically the file has more memory in it that PS can handle at one time. You can always search a PS error in Google.
