Bug Description

frpc proxy设置如下：
proxies
name = "web"
type = "http"
localPort = 8080
transport.bandwidthLimit = "20MB"
transport.bandwidthLimitMode = "server"
customDomains = ["www.yourdomain.com"]

frps 设置如下：
bindPort = 4000
log.level = "info"
log.to = "/data/frp/logs/frps.log"
auth.method = "token"
auth.token = "12345678"

webServer.addr = "0.0.0.0"
webServer.port = 7500
webServer.user = "admin"
webServer.password = "admin"

vhostHTTPPort = 8002
vhostHTTPSPort = 9002

100路并发Get下载，观察到frps侧初始cpu迅速飙升，且内存快速增长，CPU能飙高到80%左右，内存使用1.8G左右，之后会发现CPU又快速回落，甚至到0，frpc侧应该是受frps影响，cpu虽然没有飙高，但cpu也会回落到0，cpu波动较大。

反复测试后两次后，CPU表现类似，但frps的内存始终在增长，最终耗尽，被系统OOM掉

frpc Version
