我制作了一个小型 python 脚本来对我一直在开发的网站进行压力测试，然后再将其公开。它通过每 5 分钟生成一个新线程来运行，该线程在 while(true) 循环中运行以下代码。
conn = httplib.HTTPSConnection("site", 000, "pem", "pem", timeout = 30)
conn.request("GET", "/reports.php?" + url, headers = headers)
response = conn.getresponse()
read = (response.read())
如果我只有 1 个线程，那么代码请求/响应每次都会成功。当我创建新线程时，我更频繁地收到以下错误。最终，当有大约 10 个线程时，大约 90% 的时间它都会失败。

SSLError: The read operation timed out
我想知道 httplib 使用的 ssl 代码是否不是线程安全的，或者是否有其他原因导致失败？
