Bug #54612 [Asn->Fbk]: FPM+chroot: random Error 404

Edit report at https://bugs.php.net/bug.php?id=54612&edit=1 ID: 54612 Updated by: fat@php.net Reported by: erno dot kovacs at freemail dot hu Summary: FPM+chroot: random Error 404 -Status: Assigned +Status: Feedback Type: Bug Package: FPM related Operating System: Linux PHP Version: 5.3.6 Assigned To: fat Block user comment: N Private report: N New Comment: Not enough information was provided for us to be able to handle this bug. Please re-read the instructions at http://bugs.php.net/how-to-report.php If you can provide more information, feel free to add it to this bug and change the status back to "Open". Thank you for your interest in PHP. can you please catch the content of the request made from your webserver (lighthttpd or nginx) to FPM. You can use the strace command you used but just add -s 1024 or something big in order to ensure to see what FPM reads from the socket. You can also use tcpdump tcpdump -i any -s 0 -X dst port 9001 IMO the tcpdump option is the easier to implement.
