There's a limit to how many files you can have open. It looks like you're reaching
that limit. You can find out what the limit is set to (on your system) by:
cat /proc/sys/fs/file-max
the default is 4096.
You can raise the limit by, for example:
echo 8192 > /proc/sys/fs/file-max
or so I have read (I've never actually had to do this myself). You can read more
about this in the kernel docs.
