Trying to upload a small .png to Drupal. PHP 5.3.8, CentOS 5.6 x64, nginx 1.1.3 Everything else seems to work fine, but can’t seem to get any deeper information as to why anything is getting messed up. Not sure if the debug log has any hints or not. (note I also tried nginx 1.0.8) - does this debug log help with anything? or is this “probably PHP”? [http://pastebin.com/E1kDBegW](http://pastebin.com/E1kDBegW) Thanks ---

Looking more closes on php side is a way to go. Maxim D. ---

if you are using php-fpm over fastcgi i would guess its due to fpm’s request\_terminate\_timeout because the upload took too long ---

Are you able to upload other types of files? If so, I have seen this type of behavior before. It has happened after PHP version upgrades. Darn near drove me crazy as I could never trace it. It resolved with recompiling of php and all modules, including pecl modules. Just a thought. YMMV, of course. > Thanks > > * * * > > nginx mailing list > [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) > [mailman.nginx.org archive](http://mailman.nginx.org/mailman/listinfo/nginx) – Jim O.
