Ulimit copy problem
I have so many Gigabytes and as such so many files on my copy account this message will pop-up at some point in time.
The open file ulimit level is too low, please increase it otherwise changes will not be detected properly.
The fix is this :
sudo touch /etc/sysctl.d/60-copy.conf
sudo gedit /etc/sysctl.d/60-copy.conf
Copy/paste these two lines in the document that just opened up.
fs.inotify.max_user_watches = 20000
fs.file-max = 800000
sudo sysctl -p /etc/sysctl.d/60-copy.conf
