You need to increase the system limit (e.g. on Linux,
"echo 10000 > /proc/sys/fs/file-max" as root, which lasts until the
next reboot) as well as the shell limit.

I agree. Ideally it would print a message saying that the system and/or
shell fd limits are the problem, with the URL of a web page on how to
fix it.
