kcptun服务器端进程被系统kill #425

系统

server:debian 8 x64
client:archlinux x64

kcptun版本

server:version 20170322
client:version 20170322

问题描述

服务器端运行一段时间后，进程会被系统kill，systemctl start kcptun_new.service后即可恢复，一段时间后再次被kill。
仅运行服务，不跑流量，不会被kill。
问题与#422相似。

moby/moby#7087
这个看上去是systemd的问题， 没有忽略掉Sigpipe信号

相关问题， 看来这是个坑。

根据讨论1.6之后的go版本不会出现此问题，我是1.8编译的，应无此问题，也从未出现过此情况。

可以在下一个版本尝试忽略掉sigpipe信号。
