运行transmission出现错误：

transmission-daemon[32127]: UDP Failed to set receive buffer: requested 4194304, got 425984
transmission-daemon[32127]: UDP Failed to set send buffer: requested 1048576, got 425984

解决方法:

位置/etc/sysctl.conf

增加两行：

net.core.rmem_max = 16777216
net.core.wmem_max = 4194304

重新载入参数：

sysctl -p

重启transmission服务：

systemctl status transmission-daemon
