The HP-UX kernel has a default stack size of 8MB(?) per process.
You need to extend maxssiz and recompile the kernel (and reboot).
You can use SAM to do this.
(While at it, check out the maxdsiz parameter for the maximum amount
of data a program can use. It depends on your applications, if the
default of 64MB is enough or not.)
