linux – TCP缓冲区不断填满(Recv-Q full)：命名为无响应

Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address               Foreign Address             State      
udp   1894912      0 10.0.64.150:53              0.0.0.0:*

(它会一直“填充”,直到它崩溃)

尺寸：

/proc/sys/net/core/optmem_max:20480
/proc/sys/net/core/rmem_default:8388608
/proc/sys/net/core/rmem_max:8388608
/proc/sys/net/core/wmem_default:229376
/proc/sys/net/core/wmem_max:229376

netstat -su中的结果：

Udp:
426057 packets received
37152 packets to unknown port received.
2350589 packet receive errors
517422 packets sent

谁有想法？

通过将绑定日志设置为本地文件来解决：

logging{
  channel bindlog {
    file "/var/log/named/bind.log" versions 3 size 5m;
    severity info;
    print-time yes;
    print-severity yes;
    print-category yes;
  };
  category default{
    bindlog;
  };
};
