Change inotify limit
by Tianren Liu
add file /etc/sysctl.d/100-inotify.conf with following
# Increase inotify availability
fs.inotify.max_user_watches = 524288
Run sudo sysctl --system to update sysctl.
Run sysctl fs.inotify.max_user_watches to verify.
If the limit is not changed, it may be overwritten by another conf file. The output of sudo sysctl --system provides clues.
