为什么在1024个连接后连接被拒绝? [英] Why do I get connection refused after 1024 connections?

问题描述

我正在服务器和客户机都位于同一服务器上的本地Linux服务器上进行测试.在大约1024个连接之后，在我的代码中(我连接的地方)，连接被拒绝.起初，我认为select的fd_set_max限制为1024，并将服务器更改为轮询而不是select进行轮询，但我仍然没有超过这个数字.我的ulimit -n设置为2048，我监视服务器上的lsof，它达到大约1033(不确定这是否是确切的数字)并且失败.非常感谢您的帮助.

I am testing on a local Linux server with both the server and client in the same server. After about 1024 connections, in my code, where I connect, I get connection refused. At first I thought it was the fd_set_max limit of 1024 for select and changed the server to do poll instead of select and I still don't get past this number. My ulimit -n is set to 2048 and I monitor the lsof on the server it reaches about 1033 (not sure if this is exact number) and fails. Any help is much appreciated.

推荐答案

因此，经过更多研究..看来我的服务器端侦听的队列深度为20.我认为这就是原因.你们中有人也认为这是问题所在吗?

So, after a little more research.. it looks like my server side listen is having a queue depth of 20. I am thinking thats the reason. Do any of you guys think thats the problem too?
