VLang `dial_tcp失败`

Question

我正在尝试编写一个简单的多线程vlang应用程序，调用'http://www.google.com‘和'http://www.bing.com’各50次，并计算响应大小。但我为多个请求获取了dial_tcp failed：

代码如下：

module main

import net.http
import sync.pool

struct IResult {
    u string
    c int
}

fn sprocess(pp &pool.PoolProcessor, idx int, wid int) &IResult {
    item := pp.get_item<string>(idx)

    resp := http.get(item) or {
      println('Err [ for $item ]: $err.msg')
      return &IResult{
        item,
        0
      }
    }

    return &IResult{
      item,
      utf8_str_len(resp.text)
    }
}

fn main() {
    mut pp := pool.new_pool_processor(callback: sprocess)
    pp.work_on_items(['http://www.google.com', 'http://www.bing.com'].repeat(50))

    for x in pp.get_results<IResult>() {
        println('$x.u len = $x.c')
    }
}

我已经用最新的主控程序(1b9eef7)尝试了相同的代码，它在run和直接调用二进制文件(./main)时都工作得很好。

使用系统上存在的libssl-dev。考虑升级V并使用libssl-dev
