ENOSPC: System limit for number of file watchers reached

Hey thanks for the report :) Is there something in your .yarn/cache folder? If yes, try adding that to .nxignore too. I'm reworking the watching process right now so this should be fixed in the next release.

No, there is no .yarn/cache folder.
I see a .yarn/releases folder with 1 file in there: yarn-1.22.19.cjs @ 5.1mb.

Thank you for looking into this!

:) Does it say which files are being watched? Is it really node_modules?

Is it really node_modules?

I am fairly confident.

I opened the file /proc/1641254/fdinfo/31 where 161254 is the PID for the node nx-console process launched inside the dev container. This file has over 20,000 inotify handles listed.

I picked some lines at random from that file to see an output like this:

inotify wd:1386 ino:620714 sdev:10300002 mask:3ce ignored_mask:0 fhandle-bytes:8 fhandle-type:1 f_handle:140762004f31d27d
inotify wd:1385 ino:620716 sdev:10300002 mask:3ce ignored_mask:0 fhandle-bytes:8 fhandle-type:1 f_handle:160762009c51bf25
inotify wd:1384 ino:620713 sdev:10300002 mask:3ce ignored_mask:0 fhandle-bytes:8 fhandle-type:1 f_handle:1307620001620b39
inotify wd:1383 ino:621c31 sdev:10300002 mask:3ce ignored_mask:0 fhandle-bytes:8 fhandle-type:1 f_handle:311c62001e6e829c

Then, using a simple script, I traced back the inode for those files, and each of them was a file inside node_modules:

• 621c2f = /node_modules/@babel/preset-env/node_modules/@babel/plugin-transform-reserved-words/node_modules/@babel/core/lib/config/validation
• 620714 = /node_modules/@babel/preset-env/node_modules/@babel/plugin-transform-reserved-words/node_modules/@babel/core/lib/config
• 601130 = /node_modules/zone.js

Hope this helps.
