I know how to do the former, but I am not sure > about the latter. This (set MAXSSIZ in the same way as MAXDSIZ) is the best answer. There is no point in making it more tunable than MAXDSIZ. Notes: - MAXSSIZ used to be an option, just like MAXDSIZ. There are ifdefs for both in <machine/vmparam.h>. This was broken by not putting MAXSSIZ in sys/conf/options. - the stack size should normally be limited using login.conf or the stack size rlimit. These don't apply here because MAXSSIZ gives the maximum that can be set using these.
