For a simple progam using setrlimit(R_DATA), ...) with rlim_max=410_000_000_000 fails. Testcase: --- snip --- #include <stdio.h> #include <sys/resource.h> int main() { struct rlimit lim = {410*1000*1000*1000ull, 410*1000*1000*1000ull}; // does not work // struct rlimit lim = {420*1000*1000*1000ull, 420*1000*1000*1000ull}; // works if (setrlimit(RLIMIT_DATA, &lim) == 0) printf("it worked\n"); else printf("it failed\n"); } --- snip ---
