我正在尝试测试Apache模块。我正在使用python脚本打开HTTP连接并在服务器上发送数千个json数据包。每个数据包都是单独的请求。问题是我相信我在apache中遇到堆栈溢出，这显然会导致它崩溃。这是gdb输出：

mymodule.cpp的550行在处理程序中：
apreq_handle_t *req = apreq_handle_apache2(r);
在SIGSEGV发生之前，帧数突然接近我发送的数据包数。
python脚本基本上是：
def main():
conn = httplib.HTTPConnection("127.0.0.1", 8080)
headers = {
"Content-type": "application/json",
"Accept": "text/plain",
"Connection": "keep-alive"
}
with open("logfile.txt") as f:
packets = f.readlines()
for packet in packets:
conn.request("POST", "/url", packet, headers)
response = conn.getresponse()
data = response.read()
conn.close()
在模块中，解析请求主体所花费的时间线性增加但我在代码中找不到任何递归。所以我被卡住了。也许mod_reqtimeout模块与Keep-Alive连接不兼容，或者我的测试脚本有问题？
编辑：从httpd.conf中删除mod_reqtimeout似乎解决了这个问题。我面临的另一个问题是，如果测试脚本被杀死，apache也会收到SIGHUP。我怎样才能阻止这种情况发生？
