The “tail: inotify assets exhausted” error often happens if you end up utilizing the tail command to observe a file that’s being actively written to, and the inotify watch restrict has been reached.
To repair this concern, you possibly can strive growing the inotify watch restrict by modifying the /proc/sys/fs/inotify/max_user_watches file. This information will present you the way and clarify what inotify is and what it does.
Let’s get began!
Right here’s how you are able to do it:
- First, open the /and many others/sysctl.conf file in a textual content editor:
sudo nano /and many others/sysctl.conf- Add the next line on the finish of the file:
fs.inotify.max_user_watches = 524288- Save the file and exit the textual content editor.
- Apply the modifications by working the next command:

Purposes will obtain the “inotify assets exhausted” error once they attempt to add new watches when this restrict is reached. The inotify watch restrict could be elevated by modifying the /proc/sys/fs/inotify/max_user_watches file.
About sysctl
