That might require a restart of daemons that inherit the ulimit. Your
current shell prob also had it set. If you want to be safe, reboot.

Yes, you can attach to pluto as well, though I can't see why it would
crash but not core dump if kill -6 works.

cd openswan-2.6.23/OBJ*/programs/pluto
gdb -p PidOfPluto
cont

then crash it, and you should be in gdb for the "bt full" backtrace.
