I'd avoid huge numbers like that--you may be causing other problems
because you are overcommitting memory.  Just try using the same value
you have had success with via ulimit:  16384000  (in bytes).

How about calling Process.setrlimit in Ruby and then forking to
run your actually code?

Process.setrlimit Process::RLIMIT_STACK, new_limit, new_max

child = fork { do_work }
Process.wait(child)
