It works without ulimit on earlier kernels but sure enough this
fixed it on 22-pre5. Thank you!

I assume ignoring ulimit was a bug that is now fixed?

Setting /proc/sys/fs/file-max to 60000 results in a max of 1024 file
handles. In 2.4.21-rc7-ac1 and random earlier kernels this works as expected.

---------------------------------------------------------------------------

root@athlon:/root # cat file-max.c
#include <sys/time.h>
#include <sys/resource.h>
#include <unistd.h>

main() {
        int i = 0;
        struct rlimit r;
        getrlimit(RLIMIT_NOFILE, &r);
        r.rlim_cur = 50000;
        setrlimit(RLIMIT_NOFILE, &r);
        while(1) {
          if(fopen("/tmp/file-max-test", "w") == 0) {
            perror("");
            break;
          }
          i++;
        }
        printf("opened %d files\n", i);
}
