Dear Colleagues,

I have problem with nginx + php5-fpm which truncate long requests. If request POST data is longer than about 24kB not complete POST is sent to php process. I have nginx 1.0.2 installed on Ubuntu and nginx 0.8.54 installed on Debian Lenny and on both systems I experience same problem. I have never have that problem on nginx 0.8 and php installed on Windows. This is not a matter of permissions to proxy_temp directory which are correct (even when 777 is set problem still occurs, moreover permission denied was never written to error log) . I have tested many configuration settings (proxy_buffer and many fcgi settings) but nothing helped.

Could you please help me resolve that problem? Do you know what that error may be caused by?

Thanks in advance!
Paweł

Please find my nginx.conf (from ubuntu) below:

Hello,

sorry, I don't have any answer to your issue but I can only stress that I get the same thing on my server.

I have a form with long lists of multiple SELECT. When the size of submitted values reaches over 24kb, only the first 24kb of the request is used, which means the rest of the form doesn't get transmitted.
Nothing shows up in error log.

I also tried changing permissions of cache directories, changing buffer size limits and accepted body size as well but in vain.

Did anyone have this issue and found a way around ?

Not sure, still getting it to work but it may come from suhosin module in PHP...

In my case, it did come from Suhosin config.
Just added a few lines in PHP-FM ini file to allow more POST variables and after a reboot it seems to work just fine:

suhosin.post.max_vars=2500
suhosin.request.max_vars=2500

Hello Agir,

Thanks a lot for answer. I will test it ASAP and let you know if it helps.
