Increasing Inotify Watches Limit#

After upgrading to PyCharm 2017.2 the notice came that inotify value was too low and the IDE would fallback to recursive directory scanning.

$ cat /proc/sys/fs/inotify/max_user_watches

For now the following commands increase the inotify limit to 512k of files.

$ cat <<EOF | sudo tee /etc/sysctl.d/idea.conf
fs.inotify.max_user_watches = 524288
$ sudo sysctl -p --system
* Applying /etc/sysctl.d/idea.conf ...
fs.inotify.max_user_watches = 524288

It is still interesting why PhpStorm wasn’t complaining while the Symfony projects are much larger.
