webman中自定义进程会存在偶尔不记录日志问题

use support\Log;
Log::debug(' [x] 观众在线人数统计 ');

$stream = $this->stream;
        if (!is_resource($stream)) {
            throw new \LogicException('No stream was opened yet');
        }

        if ($this->useLocking) {
            // ignoring errors here, there's not much we can do about them
            flock($stream, LOCK_EX);
        }

        $this->streamWrite($stream, $record);

        if ($this->useLocking) {
            flock($stream, LOCK_UN);
        }
