Hi Chet,
Thank you for your response.
But it does not make sense since sbrk failure will be checked:
mp = (union mhead *) sbrk (sbrk_amt);
/* Totally out of memory. */
if ((long)mp == -1)
goto morecore_done;
The script just runs when my equipment boots up. Also it is hard to reproduce
in my environment. Only every few times of my equipment booting up, it
generates a coredump file.

It really looks like sbrk(2) is failing here, but since I don't have any way to
reproduce it, that may not be it. This could be caused by your process
exceeding its memory resource limit or your system's swap space being exhausted.
