Hey there, thanks for reporting this issue.

We'll need more info and/or code to debug this further. Can you please create a repository with the command below, commit the code that reproduces the issue as one separate commit on the main/master branch and share the repository here?

Please make sure that you have the latest version of the Laravel installer in order to run this command. Please also make sure you have both Git & the GitHub CLI tool properly set up.

laravel new bug-report --github="--public"

Do not amend and create a separate commit with your custom changes. After you've posted the repository, we'll try to reproduce the issue.

Thanks!

Hi, I'm experiencing what seems to be the same issue, or at least an error in the same file and line (MessageLogged.php:30)
I'm working on a fairly large project, and this issue appears to happen randomly. Most of the time, I notice it when I return to my PC after leaving the site inactive for a while.

I can't provide the code that's causing it because the logs only reference the Laravel framework and Pail, as you can see.

I'm also experiencing a similar issue. It seems to happens when reloading a file with a syntax error. Doesn't happens every time though

[utqinadhif]

finally, i found solution,

sudo nano /etc/sysctl.conf

edit with this:

fs.inotify.max_user_watches=524288
fs.inotify.max_user_instances=512

continue to restart
sudo sysctl -p

Also having the same issue with 12.40.2. Just randomly (like every 2 hours avg) my local server crashes. I have the exact same code on laravel cloud with nightwatch and never had any issues.
Its definitively not a code issue, because the error happens even when not clicking anything (without job & queue or anything).
Also the sysctl adjustment didnt help.

("tail: '/home/user/project/storage/pail/694e0bd94e9de.pail' has become inaccessible: No such file or directory")

likely because no activity logged, so .pail file gets stale and deleted? the tail process is still tailing on the old file and hence triggers the error.
