Hi! I'm running into an issue with too many files being opened by the server.

Sadly I could not take a screenshot of the exception, but it basically says "Too many open files".

When I inspect the number of files being opened by the Symfony process, this is what I get.

I was able to resolve this, by removing multiple node_modules directories and install them again. However I guess the process does not need to watch these files, right? I was wondering if this could be an issue inside symfony-cli? Thanks!

Do you happen to use the workers feature that is watching directories to restart processus?

Right now I can't reproduce it as I only see a fairly reasonable amount of opened files for the symfony processes:

$ lsof / | awk '{print $1, $2}' | \sort | \uniq -c | \grep symfony
   4 symfony 593
   8 symfony 95503

Looking at the details I only see mostly expected results with log and configurations files opened:

$ lsof / | \sort | \grep ^symfony

None that I know of. Are they configured automatically? I just use docker compose up -d and symfony serve. Thanks!
