> safe_asterisk calculates the ulimit based on file-max divided by two. On certain systems this value can be above the kernel max, which results in the open file limit not being applied. Some research shows the kernel max is 1024 * 1024 and I am able to successfully execute ulimit -n 1048576.
> cat /proc/sys/fs/file-max
> 2466684
> 2466684 / 2 = 1233342
> ulimit -n 1233342
> -bash: ulimit: open files: cannot modify limit: Operation not permitted
