主机显示可用但zabbix agent ping这个监控项一直没数据报错是怎么回事

[chg627]

agent端日志有个报错，大括号那里是server端的ip："failed to accept an incoming connection: from {xx.xx.xx.xx}: reading first byte from connection failed: [11] Resource temporarily unavailable. "

有大佬知道咋回事吗，用的Linux by zabbix agent active 模板

[Zabbix-get]

你本地直接ping ，能ping通么？
