What version of frp are you using (./frpc -v or ./frps -v)?
0.13

What operating system and processor architecture are you using (go env)?
GOARCH="amd64"
GOBIN="/usr/local/go/bin"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/itman/gopath"
GORACE=""
GOROOT="/usr/local/go"
GOTOOLDIR="/usr/local/go/pkg/tool/linux_amd64"
GCCGO="gccgo"
CC="gcc"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build283162280=/tmp/go-build -gno-record-gcc-switches"
CXX="g++"
CGO_ENABLED="1"
PKG_CONFIG="pkg-config"
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"

Configures you used:
frps.ini
vhost_http_port = 8080
bind_port = 7000

frpc.ini
[web01]
type = http
local_ip = 192.168.100.200
local_port = 8081
custom_domains = somedomain

Steps to reproduce the issue:
1.先断开客户端
2.请求相关域名
3.服务端有几率crash

Describe the results you received:
panic: send on closed channel

服务器报的只有这些信息，还有一个很严重的问题，就是http代理，开启一段时间就会断开

只要出现这个信息，就必须重启了，不然永远访问不了
