react System limit for number of file watchers reached code example

Example 1: system limit for number of file watchers reached

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

Example 2: Error: ENOSPC: System limit for number of file watchers reached

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
# that modifies the file watch limit to max 524,288 which consume approx. 512MB Ram for 64bit.
# reduce that number to consume less memory.

# to see if that did it run
cat /proc/sys/fs/inotify/max_user_watches

# you should see
fs.inotify.max_user_watches=524288

Example 3: Error: ENOSPC: System limit for number of file watchers reached,

Ubuntu

sudo gedit /etc/sysctl.conf

Add a line at the bottom

fs.inotify.max_user_watches=524288

Then save and exit!

sudo sysctl -p
