core dump

[regatta]

Hi everyone,

I have the core file size = 0

# ulimit -a
core file size        (blocks, -c) 0


but my users always get a core dump in there home directory (~ 2Gb)
from command called swirl (xscreensaver tool) and they always complain
that there home is almost full!!!

what's  the wrong !!?
