Hi Ming
Hi,
In /etc/profile, I do add:
*ulimit -S -c unlimited > /dev/null 2>&1
*
most of the times, I can get core file when my application crash, but
there
are a few times it does not.
Maybe you're out of disk free space? Just a guess.
Does anyone know how the core file be generated everytime application
crashes ?
From what I know, whenever the program receives signal that generates
core, then it will dump it. Look at "man 7 signal" and you can find out
which signal that does core dump by default. Also, AFAIK, the handler
actually resides in kernel space, but you're free to assign a new handler.
What could be the causes for kernel not generating core file ?
Another possibility is, the program assign a new signal handler, thus
core dump isn't executed.
regards,
Mulyadi
