Examples are Zend Optimizer, Zend Debugger, Turck MM Cache, APC, Xdebug and ionCube loader. These extensions often modify engine behavior which is not related to PHP itself.

My script outputs some part of file and waits for ipc message to continue sending file. max_execution_time is set to 0, ignore_user_abort is off. When user aborts the connection - nginx closes client connection and connection to php-fastcgi server. But the socket on php doesn't close and remains beeing in CLOSE_WAIT state without any timeout. There is also no script execution break caused by connection abort - connection_status() always returns 0. Example of netstat output: tcp 1 0 127.0.0.1:10000 127.0.0.1:42347 CLOSE_WAIT 29566/php Reproduce code: --------------- while (!$t) { if (msg_receive($GLOBALS['stream_queue'], 1, $msg_type, 1024, $msg, true, MSG_IPC_NOWAIT)) { $t = true; } else { usleep(10000); } } Expected result: ---------------- That code execution should break on user abort. Actual result: -------------- Actually it doesn't break. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37256&edit=1
