Here's what I've tried: $ ulimit -n 1024 $ ulimit -n 1024 So I tested with the following code: #include int main(int argc, char **argv) { int i; for (i = 0; i < 1000; i++) { FILE *f = fopen("/dev/null", "r"); if (!f) break; printf("%d\n", i); } exit(0); } Results: 0 1 ... 132 Segmentation fault (core dumped) So the limit appears to be 133 files. And it appears to have no relation to the ulimit command (which is probably intentional, I'm not sure if ulimit is supposed to work in Cygwin). Any ideas, anyone?
