Warning: Your system has very few file descriptors available in total.
Maybe you should try raising that by adding 'fs.file-max=100000' to your
/etc/sysctl.conf file. Feel free to pick any number that you deem appropriate.
Then run 'sysctl -p'. See /proc/sys/fs/file-max for the current value, and
file-nr in the same directory for how many of those are used at the moment.
