Go back to the categories of Error Identifiers.
This error is logged when the errdaemon is started and when the checkstop count in nonvolatile random access memory (NVRAM) indicates that a checkstop has occurred. The errdaemon copies the checkstop data from NVRAM to a file and records the path name of the file and the checkstop count in the error log entry. The errdaemon resets the checkstop count to zero.
Note: When a machine checkstops, the machine will try to reboot itself. If the reboot is unsuccessful, the system will attempt to reboot itself two more times. If each subsequent reboot is unsuccessful, the machine will stop with the value 201 in the operator display panel. If this occurs, contact your service representative for assistance.
| Checkstop Count | The value of the checkstop count from NVRAM. |
| Checkstop File Pathname | |
| Path name of file where checkstop data was saved. | |
Error Description: SOFTWARE PROGRAM ABNORMALLY TERMINATED
This error is logged when a software program abnormally terminates and causes a core dump.
| Signal Number | The decimal value of the signal number received at program termination. |
| User's Process ID | The decimal value of the user ID on which the terminated program was running. |
| File System Serial Number | |
| The decimal value of the file system serial number for the core file generated. | |
| I-node Number | The decimal value of the i-node number relating to the core file. |
The file-system serial number is assigned to file systems at mount time and represents the order in which mounts occurred. This serial number identifies the file system in which the core dump occurred. The i-node number identifies the directory that contains the core dump file.
Mounted file systems are associated with a linked list of virtual file system (VFS) structures. You can locate the corresponding VFS serial number as follows:
Note: The filesystem serial number is not guaranteed to be useful following a system restart since it depends on the mount sequence.
