Overview Description

Large memory leaks are visible at short intervals iteration


  1. Setup bundle to the application;
  2. Replace CodeMeme\Bundle\CodeMemeDaemonBundle\Command\ExampleStartCommand::execute on:

    protected function execute(InputInterface $input, OutputInterface $output)
      $daemon = new Daemon($this->container->getParameter('example.daemon.options'));

      while ($daemon->isRunning()) {

  1. Run command:
./app/console example:stop
  1. Run top(or another activity monitor) and see results;

Actual Results

Occupied memory is growing at 500kb per minute at an interval of 100 ms

Expected Results

No leakage

Additional Information

I found a reason. System_Daemon::setOptions in the Daemon::isRunning method causes memory leaks. I can not understand why we update the parameters at each iteration.


thanks for fixing this. I merged your pull request.
