Is this script/program written by yourself?

This can happen if you try to access "forbidden" memory areas, e.g. with a wrong pointer or cast.

If you do a

# file core

you get the application that was causing the dump.

The problem occurred at line 238 of the script called upsupdate. At that line, a process was started that had the process ID of 29247. Whatever directory this shell script was in, there will be a file called core which you can decode with:

file core

This will only tell you the program's name, not the reason that it failed. Contact the programmer that wrote the program.

Memory fault occurs:
1: Subscripting arrays past the memory allocation for your program.
2: A NULL or unitialized pointer, subscript out of range.
3: Attempts to reference data outside valid address space
4: Parity errors in address space
5: Recursion (try making your own routines "read" and "write" and then call "scanf" or "printf" and watch what happens).

Check these resons in ur script.
