my output of `ulimit -a' is:

core file size (blocks) 20000
data seg size (kbytes) unlimited
file size (blocks) unlimited
max locked memory (kbytes) unlimited
max memory size (kbytes) unlimited
open files 1024
pipe size (512 bytes) 8
stack size (kbytes) unlimited
cpu time (seconds) unlimited
max user processes 256
virtual memory (kbytes) unlimited
my be you have a limit for the stack size.
