I've seen this "too many open files" error before. It's usually an
operating system problem and you need to increase the open files limit
for your operating system. This happened to me in Linux and I'm not sure
if it can happen on other operating systems, too.

You can check to see what the limit for file descriptors is by running:

$ cat /proc/sys/fs/file-max

Mine is set to 303573. You might even need to increase it beyond this
depending on your server. To increase this limit, I would just do a
Google search for 'too many open files" error as there are many
tutorials out there.

If you increase the OS file descriptor limit and are still having
problems, please post back!

Some instructions for increasing the open file limit are available at the
top of this workitem:
