red_connect_relay failed!!!: Too many open files

[ysun]

Hi, I got a failure:

1582741581.368003 notice main.c:255 main(...) redsocks started with: epoll
1582741582.989604 err utils.c:141 red_prepare_relay(...) socket: Too many open files

My redsocks.conf:

base {
        log_debug = off; 
        log_info = on;
        log = stderr;
        daemon = off;
        redirector = iptables;
        reuseport = off; 
}
redsocks {
        bind = "127.0.0.1:12345"; 
        relay = "10.239.48.147:80"; 
        type = socks5;
                                                                                     
        autoproxy = 0; 
        timeout = 10; 
} 
 
autoproxy { 
    no_quick_check_seconds = 60; // Directly relay traffic to proxy if an IP 
    quick_connect_timeout = 3;   // Timeout value when performing quick 
} 

command of iptables: iptables -t nat -A OUTPUT -p tcp -j REDIRECT --to-ports 12345 iptables -t nat -A OUTPUT -d 127.0.0.0/8 -j RETURN

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
RETURN     all  --  anywhere             localhost/8
REDIRECT   tcp  --  anywhere             anywhere             redir ports 12345

I'm not expert of network, could you guide me a little bit, what's wrong here? Thanks

This issue is usually caused by redirection loop. follow examples here https://github.com/darkk/redsocks/blob/master/README.md

or, you can google it. Many people met the same problem.

hello if the upstream proxy does not respond , redsocks keeps the idle connection until it times out , and if the incoming load is large , it runs out of ports and logs those messages ; this is just by experience ; in my case i had configured the upstream proxy with its DNS name ; and someone changed the IP of that name ; this seems to have caused this issue ! HTH Regards

的确是BUG， 用 https://github.com/darkk/redsocks 编译的，HTTP代理就正常，可以排除loop

[semigodking]

那就奇怪了，得研究一下

redsocks 在早期也有这个BUG，修复过 https://github.com/darkk/redsocks/issues/90

[semigodking]

我没有用过HTTP代理。我都是使用其他代理。每天都在使用，从没有出现过这种问题啊。
