Increasing the stack size may worsen the problem.  If the problem
is that the program is threaded and it's creating more threads
than your process can support, increasing the stack size would
probably make the problem worse.  If, on the other hand, the problem
is due to runaway recursion, you can't fix that with *any* kernel
parameter; only those responsible for maintaining the source
code can fix it.
