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?

  • You will have to be more specific.

Reset to default
11

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. :)

  • 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.
