From: Operating system: Ubuntu 10 , 64Bit PHP version: 5.3.7RC4 Package: Unknown/Other Function Bug Type: Bug Bug description:AMQP::consume()
Description: ------------ --- >From manual page: http://www.php.net/amqpqueue.consume --- Using this against a RabbitMQ server... This is a very small snippet of very simple code. If you use the consume on a durable message on a durable queue, this just eats up memory, and kills teh machine, when it hits around 7k messages. Using get() all is Ok. It looks like a memory leak somewhere in teh AMQP code.... Test script: --------------- include_once('../config/config.php'); $nMessNum = 4000; $nCount = 0; $nTimeLimit = 600; $nI = 0; $sMessRoute = ''; while($nI++ < 10000){ $sMessRoute .= 'a'; } $nstart = microtime_float(); $amp = new AMQPConnection($RABBIT_SERVERS); if($amp->connect()){ echo('Connected to Host'."\n"); // Declare a new exchange $options = AMQP_DURABLE; $ex = new AMQPExchange($amp,'stone_warren'); $ex->declare('stone_warren', AMQP_EX_TYPE_FANOUT, AMQP_DURABLE); // Create a new queue $q = new AMQPQueue($amp); $q->declare('queue1',AMQP_DURABLE); // Bind it on the exchange to routing.key $ex->bind('queue1', 'routing.key'); // consume a message to the exchange with a routing key...and ack it. $options = array( 'min'=>1, 'max'=>10, 'ack'=>true ); $nMsgCount = 0; $tsStart = time(); while(1){ // Forever $nCount++; // This dies soon... after about 7k messages $msg = $q->consume($options); //$msg = $q->get(0); echo(print_r($msg, true)."\n"); usleep(10000); if((file_exists('consumer'.$nType.'.stop')) || ((time() - $tsStart) > $nTimeLimit)){ break; } } }else{ echo("Failed to connect \n"); } // END OF CODE Expected result: ---------------- Should run forever, consuming messages placed on the queue by a similar process. Using get() I was able to process 23m messages over a 3 day period. Using consume(), I die in a matter of minutes. -- Edit bug report at https://bugs.php.net/bug.php?id=55384&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55384&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55384&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55384&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55384&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55384&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55384&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55384&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55384&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55384&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55384&r=support Expected behavior: https://bugs.php.net/fix.php?id=55384&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55384&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55384&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55384&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55384&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55384&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55384&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55384&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55384&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55384&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55384&r=mysqlcfg
