UNIX for Dummies Questions & Answers

I am using Unix OpenServer Release 5.

When a run a application with user different to "Superuser" the application give me the following error:
"Memory Fault - Core Dump". What's that mean?

Thank you in advance.

Hi

This happens when there is some sort of conflict within memory. A file called "core" is produced. This contains an image of the memory at the time the problem occurred. There are packages available to examine the "core" file to find out where the memory conflict occurs. But, its not always easy to trace the error.

There could be numerous reasons why this is happening. It could be that he application could require permissions or environment variables which are only available to the superuser. Although it may be just "luck" that the core dump does not happen as "superuser", such is the nature of memory faults. Do you have the source code to the application? If so, it may be worth checking the permissions/env variables theory within the code. It could also be a totally unrelated error in the source code.

Sorry to be vague, but memory faults are unpredictable by nature and difficult to track down without usually a great deal of investigation.

Good luck!
