You can use the ulimit command in either the /etc/profile or in individual login ID's .profiles to set the size limit for the core file: ulimit 200000

unfortunately, neither the man pages for ulimit or core really address this.

Hi

/etc/rc.config.d/savecrash

# SAVECRASH: Set to 0 to disable saving system crash dumps.
SAVECRASH=1
ensure that it is set to 1.

And savecrash_dir is set to your required dir.

You mean you want to limit the core file size because I think you can't control where the core file is generated, you can only limit its size. Also you might want to check out SAM->RoutineTasks->SystemLog
which allow you to manage your system log files. To limit the core file size ..
(in POSIX shell, check ..)
# man setrlimit
==> allows you to set a max size on a core file for a process and its child processes.

Also you can use "ulimit -c" to set the max core dump size (for instance ..)
# ulimit -c 4096
==> would limit core for all children of the shell to 2MB.

Hi Ramesh,

If you talking about the system crash files, the config file is /etc/rc.config.d/savecrash in 11.0. It should be /etc/rc.config.d/savecore in 10.10. You can modify the directory where the crash dump will be saved in this file. The command to save a previous core dump manually should be

savecore -vr

Hope this helps.
