I assume you mean core files not system dumps. In order to enable full
cores you must do 2 things, one of which you sound like you have done. In
/etc/security/limits file set core = xxx where xxx is 512 byte blocks. Then
the thing I think your missing is set the fullcore attribute of sys0, i.e.
# chdev -l sys0 -a fullcore=true
You can check the value with
# lsattr -El sys0
If you do this you'll notice a pre430core attribute for CHRP based machine,
generaly I leave that alone.
Good Luck, and feel free to re-post or send me e-mail if that doesn't help.
