Node.js: what is ENOSPC error and how to solve?

Question

I have a problem with Node.js and uploading files to server. For uploading files to server I use this plugin. When starting file upload to the server, Node.js process crashe

Answer 1

A simple way that solve my problem was:

npm cache clear

npm or a process controlled by it is watching too many files. Updating max_user_watches on the build node can fix it forever. For debian put the following on terminal:

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

If you want know how Increase the amount of inotify watchers only click on link.

Answer 5

It indicates that the VS Code file watcher is running out of handles because the workspace is large and contains many files. The max limit of watches has been reacherd, you can viewed the limit by running:

cat /proc/sys/fs/inotify/max_user_watches

run below code resolve this issue:

fs.inotify.max_user_watches=524288

Rebooting the machine solved the problem for me. I first tried wiping /tmp/ but node was still complaining.
