目前发现在调用第三方提供的地址的时候出现死循环（没办法安装满足lbt工具运行的gdb和python[生产环境]），gdb跟踪发现一直在ngx_http_lua_socket_receiveuntil_iterator与ngx_http_lua_socket_tcp_receiveuntil中循环执行，运行1天甚至更多天后会挂死一个进程。
调用了ngx_http_lua_socket_tcp_receiveuntil函数处只有resty.http库，主要用途利用resty.http请求第三方地址。
请求示例如下
local http = require("resty.http")
local hc = http:new()
hc:request {
method = "GET",
url = "">
}
hc:request使用前后都有输出日志，在使用前的日志输出正常，使用后的日志没有输出。
有什么办法可以知道到底是什么导致陷入死循环了么？
对照堆栈看代码也没看出结果来，只知道在ngx_http_lua_socket_tcp.c中每次都是执行在下面两句代码后，开始下一次循环，在resty.http库中也没看出出错的地方。
