hi guys, i have a serious problem that i can’t make nor heads nor tails of. i am using nginx 1.0.6 with php 5.2.17 + fpm. i run a gallery2 image gallery, pretty busy, and when i redirected some traffic from the old server today to the new one, i got a bunch of memory leaks messages in the php-fpm log. they are going like crazy filling up the log. can you please give me some advice? thanks in advance.

You will want to bring this up to the PHP people as there is no link between Nginx and PHP-FPM. There is a fastcgi abstraction layer between them. That said, they have deprecated PHP 5.2.x and PHP-FPM for 5.2.x is a patch so I honestly think you’ll be told to upgrade first and then see what happens, so you might want to do that first.

fixed by disabling the apc extension. i have no clue how that got installed as i did not build it. it was conflicting with the installed eaccelerator. weird stuff. ---

FYI: last version of APC (3.1.9) fixed some memory leaks with FastCGI, I have no issues with php-fpm 5.3.8 and APC 3.1.9 another recomendation - switch to PHP 5.3 if you can, 5.2 branch is not supported anymore, and php-fpm SAPI is now bundled into main PHP (5.3), works fine, just pay attention that config file is not XML anymore.
