When a system error occurs, the system usually displays a dialog box that includes a bomb icon and an error code.
Error codes vary depending on the nature of the cause.
To help identify the cause of the error, make sure to note any codes you receive. If the system returns errors with different codes, there may be a problem that affects more than one of its functions. Other causes could include faulty application code, a defective SCSI connection, or a bad logic board. Because these causes are less likely causes, you should for them only after troubleshooting for the most common causes. When either of these errors occur in only one application, try running the application with extensions disabled.
