Question

How can we invoke a segmentation fault/core dump for any daemon process without code access ?

Send it a `SIGSEGV` or `SIGBUS` signal. – Jean-Baptiste Yunès Nov 25 '15 at 12:24 — Jean-Baptiste Yunès, Nov 25 '15 at 12:24
from the command line: `kill -segv (your-daemon-pid)` – geert3 Dec 02 '15 at 19:20 — geert3, Dec 02 '15 at 19:20

AIX has a command 'gencore' [1] that you can use to request a core dump without a segmentation fault or any other interruption.

kill -11 of the process or the daemon, when segmentation fault happens OS will do core dump. Here we are faking a segmentation fault by sending the SIGSEGV( 11 ) to it. Refer to /usr/include/sys/signal.h to check the number of the signal.
