The running server takes all the resources of one core of the CPU. #27

When I started the app server using bin/console swoole:server:run, I've got load average of a core of a processor in 100%. At the same time, I do not make requests to the site.

My php version is

Also I tried https://github.com/zendframework/zend-expressive-swoole and it works fine with zend expressive. The load average of CPU was low in idle mode.

Hello @debugger84, the one thing that comes to my mind, and could be responsible for that, is working hmr. It is enabled by default when inotify php extension is installed and you're in debug mode.

Could you please try setting hmr: off in your bundle config file? https://github.com/k911/swoole-bundle/blob/develop/docs/configuration-reference.md

Hello @k911, you are right, thank you. Switching value of the swoole.http_server.hmr field to "false" has repaired the problem.

@debugger84 I'll close this issue, since I believe problem is solved. If that's not the point please feel free to reopen.
