出现“ReactorNotRestartable: （反应堆不可重启）”错误，不太理解是什么意思，要专门解决？

出现“ReactorNotRestartable: （反应堆不可重启）”错误，不太理解是什么意思，要专门解决？
           这段代码已运行就出现[*]，然后只能重启服务。以下两个问题错误类似，麻烦同志们解答以下。
运行的代码1：

使用Twisted创建简单服务器

from twisted.internet import reactor
from twisted.internet.protocol import Protocol,Factory

class SimpleLogger(Protocol):
    
    def connectionMade(self):
        print('Got connection from',self.transportr.client)
        
    def connectionLost(self,reason):
        print(self.transport.client,'disconnected')
    
    def dataReceiveda(self,data):
        print(data)
        
factory = Factory()
factory.buildProtocolpro = SimpleLogger

reactor.listenTCP(12345,factory)
reactor.run()
运行结果及报错内容 ：

运行的代码2

使用协议LineReceive改进后的日志服务器

from twisted.internet import reactor 
from twisted.internet.protocol import Factory 
from twisted.protocols.basic import LineReceiver
    
class SimpleLogger(LineReceiver): 
    def connectionMade(self): 
        print('Got connection from', self.transport.client) 
    def connectionLost(self, reason): 
        print(self.transport.client, 'disconnected') 
    def lineReceived(self, line): 
        print(line) 
        
factory = Factory() 
factory.protocol = SimpleLogger 

reactor.listenTCP(1234, factory) 
reactor.run()

用多进程试试
