Copy app error: "The open file ulimit level is too low, please increase it otherwise changes will not be detected properly"

Question

When using Copy, I get this error:

Error: "The open file ulimit level is too low, please increase it otherwise changes will not be detected properly"

The application stops syncing when it appears, why, and how do I fix it?

@psusi: Thanks for your comment. I made the question more clear. I just wish to contribute to askubuntu writing this answer. — pablofiumara, Apr 25 '14 at 03:31

1) Create file /etc/sysctl.d/60-copy.conf

2) Open that file and write:

fs.inotify.max_user_watches = 20000
fs.file-max = 800000

3) Save the file and exit

4) Go to the terminal and apply those settings by typing:

sudo sysctl -p /etc/sysctl.d/60-copy.conf

5) Launch the Copy app again and it should work.

I don't know what this app is since the link you gave is dead and gone. But if you are going to suggest adding files to /etc/sysctl.d, please read the README in that directory first. :) – chaskes Apr 26 '14 at 03:06

@chaskes: Thanks for your comment. This is app is competing against Dropbox. For more information, please see the app's tag wiki. – pablofiumara Apr 26 '14 at 06:02
For some reason this only worked for me *once*. After that I tried increasing the limits even 100 times more than this and I couldn't get the CopyAgent to start. – Mike Oct 17 '15 at 21:05
