Hi All,

I understand that this is a generic error, but it has been frustrating
trying to solve this issue and i'm not able to find an answer anywhere.
basically i have an application which is running fine using apache, but we
wanted to try nginx/php5-fpm:

some parts of my application has this connection reset issue, sometimes it
works but inconsistent.
if it does not work, i restart php5-fpm and it will work again, but after
sometime it will have the same issue.

i'm using:

# nginx -v
nginx version: nginx/1.4.0

# php5-fpm -v
PHP 5.4.14-1~precise+1 (fpm-fcgi) (built: Apr 11 2013 17:18:51)
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies

when i enable debug this is the only thing i can see;

[08-May-2013 18:08:32.545758] DEBUG: pid 358359, fpm_got_signal(), line 72:
received SIGCHLD
[08-May-2013 18:08:32.545884] WARNING: pid 358359, fpm_children_bury(),
line 252: [pool legacy] child 358423 exited with code 3 after 342.958315
seconds from start
[08-May-2013 18:08:32.548943] NOTICE: pid 358359, fpm_children_make(), line

[08-May-2013 18:08:32.549023] DEBUG: pid 358359, fpm_event_loop(), line
411: event module triggered 1 events


i have tried different config changes like using static instead of
dynamic..increase max_request..increase child ...increase server..etc.

one thing i really need is to identify what is causing that connection peer
but logs is not really helping. i tried strace and it still did not show me
anything.

any other way to debug or identify what is causing this issue? totally
clueless right now.

thank you in advanced.

Regards,
Ron
