What version of frp are you using (./frpc -v or ./frps -v)?
0.25.1

What operating system and processor architecture are you using (go env)?

Configures you used:

# file: frpc.ini
[sentry]
type=http
local_port=9000
#custom_domains=i1hao.com
custom_domains=sentry.i1hao.com

# 启用健康检查，类型为 http
health_check_type = http
# 健康检查发送 http 请求的 url，后端服务需要返回 2xx 的 http 状态码
health_check_url = /_health/
health_check_interval_s = 10
health_check_max_failed = 3
health_check_timeout_s = 3

Steps to reproduce the issue:

我使用了systemd作为“守护进程”来启动frpc，配置和log在上面
2.当frpc运行一段时间后，提示我socket: too many open files

所以，这里是frpc报的错误吗？需要修改systemd的limits？还是[sentry]这个服务的错误？
