swoole http server 整合 phalcon，ab测试，报php内存耗尽

在整合swoolehttpserver和phalcon，server.php如下：

registerDirs(array('../apps/controllers/','../apps/models/'));$loader->register();}/***Thismethodsregisterstheservicestobeusedbytheapplication*/protectedfunctionregisterServices(){$di=newDI();//Registeringarouter$di->set('router',function(){returnnewRouter();});//Registeringadispatcher$di->set('dispatcher',function(){returnnewDispatcher();});//RegisteringaHttp\Response$di->set('response',function(){returnnewResponse();});//RegisteringaHttp\Request$di->set('request',function(){returnnewRequest();});//Registeringtheviewcomponent$di->set('view',function(){$view=newView();$view->setViewsDir('../apps/views/');return$view;});$di->set('db',function(){returnnewDatabase(array("host"=>"localhost","username"=>"root","password"=>"","dbname"=>"invo"));});//RegisteringtheModels-Metadata$di->set('modelsMetadata',function(){returnnewMemoryMetaData();});//RegisteringtheModelsManager$di->set('modelsManager',function(){returnnewModelsManager();});$this->setDI($di);}publicfunctionmain(){$this->registerServices();$this->registerAutoloaders();}}$application=null;$http=newswoole_http_server("0.0.0.0",9501);$http->on('request',function($request,$response){try{$_GET=$_POST=$_COOKIE=$_REQUEST=[];if(!empty($request->get)){$_GET=$request->get;$_REQUEST+=$_GET;}if(!empty($request->post)){$_POST=$request->post;$_REQUEST+=$_POST;}if(!empty($request->cookie)){$_COOKIE=$request->cookie;}global$application;$html=$application->handle($request->server['request_uri'])->getContent();$response->end($html);}catch(\Exception$e){print_r($e);echo$e->getMessage();}});$http->on('WorkerStart',function($server,$workerId){global$application;$application=newApplication();$application->main();});#启动服务器$http->start();

浏览器访问没什么问题
做ab测试就报错了

ab-n10000-c1000-rkhttp://phalcon.com/

错误信息：

[root@localhostpublic]#[2016-08-2517:12:45*12502.0]ERRORzm_deactivate_swoole(ERROR103):Fatalerror:Allowedmemorysizeof268435456bytesexhausted(triedtoallocate16384bytes)in/srv/www/single/public/server.phponline126.[2016-08-2517:12:45$12497.0]WARNINGswManager_check_exit_status:worker#0abnormalexit,status=255,signal=0

请教这是什么原因导致的，是onRequest那里写的不对吗？
