while working with emberjs in ubunut? Don't worry! We can fix it. It is just hitting your system's file watchers limit.

To increase the file watchers limit we need to do certain things, first
enter the following command in your terminal

cat /proc/sys/fs/inotify/max_user_watches

You might get output like this some integer.
8192

Now increase the limit by entering the next command

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf

The above command will set your file watcher limit to 524288. To see whether it is set or not, type

sudo sysctl -p

output
fs.inotify.max_user_watches = 524288

Now, again run your ember server and it'll work fine.

I hope this post is helful to you, if yes then give a heart. Please comment if you have any issues. Do let me know if you need more emberjs related posts.
