[clue] ulimit

[Jason Friedman]

I am trying to enable my user to write core files on RedHat EL5.

I added to the bottom of /etc/security/limits.conf:
*       soft            core            unlimited
*       hard            core            unlimited
*       soft            nofile          20000
*       hard            nofile          20000

After restarting I can see my setting for number-of-files was
affected, but not core size:
$ ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0

pending signals                 (-i) 270336

real-time priority              (-r) 0
stack size              (kbytes, -s) 10240
