I built a console app with Symfony Console component. It supposed to be run for 5 hours. But after running 2 hours i have a proc_open(): unable to create pipe Too many open files error in Symfony\Component\Console\Application.php on line 985.
I tried gc_collect_cycles in my loop, but got the same error.
Is this a Symfony Console component bug or i should not run an app for this long (but i have to)?

Apparently you're working on a lot of resources in your app. It's not a Symfony Console bug, it's a PHP bug.
You can use another programming language or modify your program in order to open less files.
I had this same error with a Symfony web-app, and restarting PHP resolved it.
I appreciate that you can't do that in the midst of your command's 5-hour run, but maybe doing it immediately beforehand will get PHP in a clean enough state to give you the full 5 hours?
(Also, this post is the only one I found about my problem, so I wanted to add this here in case others have the same issue as me!)
