发现一个问题,provider启动时manger进程会意外退出

WARNING swServer_signal_hanlder: Fatal Error: manager process exit. status=0, signal=11.

`
class ZookeeperClient
{

public function __destruct()
{
$this->closeLog();
unset($this->zookeeper);
$this->logger->info('zookeeperClient destruct');
}

`

__destruct方法 要先unset($this->zookeeper); 再 $this->closeLog();

`
class ZookeeperClient
{

public function __destruct()
{
unset($this->zookeeper);
$this->closeLog();
$this->logger->info('zookeeperClient destruct');
}
