Intellij filewatcher less6/15/2023 ![]() You may also need to pay attention to the values of max_queued_events and max_user_instances if Listen keeps on complainingĪfter making those changes, my VSCode was once again able to track my changes, which in turn, meant that the source control features were actually helpful and I didn’t have to use the terminal to see my diffs. $ echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/nf If you like to make your limit permanent, use: $ sudo sysctl fs.inotify.max_user_watches=524288 When this limit is not enough to monitor all files inside a directory, the limit must be increased for Listen to work properly. $ cat /proc/sys/fs/inotify/max_user_watches You can get your current inotify file watch limit by executing: ![]() For example, Ubuntu Lucid’s (64bit) inotify limit is set to 8192. It’s not uncommon to encounter a system limit on the number of files you can monitor. Listen uses inotify by default on Linux to monitor directories for changes. The guard/listen repo has an informative post on the process. The fix was relatively straightforward: increase the number of watchers. There are, however, a fixed number of watchers, and evidently, my machine’s default (8192) was insufficient to the task. ![]() Watchers are part of the inotify Linux kernel subsystem 1 that extend the filesystem to notice changes and report on those changes to applications listening for them. I have been working on a Linux VM more recently, and one particularly annoying thing about it (there are a lot of little quirks that are frustrating) was that VSCode couldn’t monitor for changes because it was out of watchers.
