#49616 [Opn->Csd]: Impossible to increase SOMAXCONN

ID: 49616 User updated by: ben at realitychecknetwork dot com Reported By: ben at realitychecknetwork dot com -Status: Open +Status: Closed Bug Type: Feature/Change Request Operating System: Linux 2.6.18 PHP Version: 5.2.11 New Comment: In CentOS5.3 its actually : /usr/include/linux/socket.h Thanks, that did the trick. Replace: /* Maximum queue length specifiable by listen. */ #define SOMAXCONN 128 With: /* Maximum queue length specifiable by listen. */ #define SOMAXCONN 2048 Then recompile PHP Previous Comments: ------------------------------------------------------------------------ [2009-09-22 09:38:30] sjoerd@php.net PHP uses the SOMAXCONN from sys/socket.h at compile time. ------------------------------------------------------------------------ [2009-09-21 20:22:24] ben at realitychecknetwork dot com Description: ------------ Impossible to increase SOMAXCONN value by updating system OS variable. PHP must be compiled with --enable-sockets for this bug to be produced. OS setting updated with: # sysctl -w net.core.somaxconn=2048 net.core.somaxconn = 2048 PHP will always return 128 for SOMAXCONN and will not respect the OS setting. Additionally, it will ignore a define statement in PHP code and return 128 as well. Reproduce code: --------------- define("SOMAXCONN", 2048); echo SOMAXCONN; Expected result: ---------------- Should return 2048 Actual result: -------------- Returns 128 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=49616&edit=1
