ENFILE Error

[fkraeutli]

When running spritesheets.js on a current version of MacOS one may encounter the following error:

Error: ENFILE: file table overflow

This is because MacOS only allows a limited number of open files. To increase the limit, run:

$ echo kern.maxfiles=65536 | sudo tee -a /etc/sysctl.conf
$ echo kern.maxfilesperproc=65536 | sudo tee -a /etc/sysctl.conf
$ sudo sysctl -w kern.maxfiles=65536
$ sudo sysctl -w kern.maxfilesperproc=65536
$ ulimit -n 65536 65536

Thank you for this fix! I am still running an old OSX version and didn't encounter this.
I must admit, that the pixi-packer used in spritesheet.js does sometime crash even on my system. Running the spritesheet.js script individually a second time often fixes it.

The same goes for ubuntu:

# available limit
user@ubuntu:~$ ulimit -n
1024

# To increase the available limit to say 65535
user@ubuntu:~$ sudo vim /etc/sysctl.conf

# add the following line to it
fs.file-max = 65535

# run this to refresh with new config
user@ubuntu:~$ sudo sysctl -p
