Getting 502 bad gateway on uploading a file

Server NGINX
1

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”?

Thanks

The “recv() failed (104: Connection reset by peer) while reading
response header from upstream” message suggests PHP closed
connection for some reason (died?) right after nginx sent request
to it. Looking more closes on php side is a way to go.

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

Very unlikely, as everything happens within 1 second.

Exactly - this happens immediately like it doesn’t even try…

Alright well if the logs don’t give you any clue from the nginx side,
I’ll have to try to figure out the PHP side now :slight_smile:

Is this only happening with png’s? 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
