php – 内存泄漏symfony和monolog和控制台

我花了最后2个小时试图找到我的内存泄漏.

事实证明

>超过40k次迭代,无需记录每个n但模数为50,启动mem：28 mb end mem：30mb
>超过5k次迭代,记录每个n,无模数,启动mem：28mb,结束mem 38mb.

例

 # this leaks
 # start mem: 28 mb end mem: 38mb, n = 5k
 foreach ($this->queryData->iterate() as $j => $data):
            declare(ticks = 1);
            self::$currentAd++;
            $this->em->detach($data[0]);
            $this->logger->info(LogUtility::getMemoryUsage() . " (" . self::$currentAd .")");
            if(self::$currentAd === 40000 ):
                break(2);
            endif;
  endforeach;

 # this doesn't leak
 # start mem: 28 mb end mem: 30mb, n = 40k
 foreach ($this->queryData->iterate() as $j => $data):
            declare(ticks = 1);
            self::$currentAd++;
            $this->em->detach($data[0]);
            if(self::$currentAd % 50 == 0):
                  $this->logger->info(LogUtility::getMemoryUsage() . " (" . self::$currentAd .")");
            endif;
            if(self::$currentAd === 40000 ):
                break(2);
            endif;
  endforeach;

我的monolog配置：

 handlers:
    test:
        type:   stream
        path:   "%kernel.logs_dir%/immobilier/test.log"
        level:  debug
        channels: test
  console:
        type:   console
        bubble: false
        verbosity_levels:
            VERBOSITY_VERBOSE: INFO
            VERBOSITY_VERY_VERBOSE: DEBUG
        channels: [test]

有任何建议要纠正吗？

解决方法:

找到了解决方案.我不能告诉你这种内存泄漏发生的确切原因,但是根据this;在命令中添加–no-debug选项可以解决问题.它实际上做了,它甚至减少了2mb的内存.干杯！
