Whatever you want :) http://www.grasvezel.nl/media/software/cpuload.txt Here is a complete undressed file which only has the problem. Previous Comments: ------------------------------------------------------------------------ [2010-01-14 12:17:19] j...@php.net I asked for small, complete script NOT for a framework. ------------------------------------------------------------------------ [2010-01-14 12:13:36] jason at lentink dot net I could provide you guys with a small script bug i can also point you to the place where the problem exists since it happens in Zend Framework. http://framework.zend.com/svn/framework/standard/trunk/library/Zend/Queu e/Stomp/Client/Connection.php The function is used at line 79. What i see on my servers is that when there are simultaneous request made to the same script the problem increases more rapidly. ------------------------------------------------------------------------ [2010-01-13 12:07:10] j...@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2010-01-13 09:58:52] jason at lentink dot net Description: ------------ When using stream_set_blocking on a stream will create a huge load on cpu. When using this function it uses up to 50% of the cpu. When not using this function it will only use 0.1% cpu usage. Reproduce code: --------------- $this->_socket = fsockopen($str, $port, $errno, $errstr); stream_set_blocking($this->_socket, 0); // non blocking Expected result: ---------------- An socket which will be opened fast. in a non-blocking mode. Actual result: -------------- An open socket. But the cpu use is enormous. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50737&edit=1
