You should increase the max file descriptor limit by
ulimit -n 51200

here is more optimizations for your server https://github.com/shadowsocks/shadowsocks/wiki/Optimizing-Shadowsocks

It seems there was no more available port to be allocated, the OS was complaining. I have to point out that there is a potential resource leak in the current code, for which I am responsible.

The udp module was initially created by me a few months ago, to solve #26. It is not so well designed(I supposed that people seldom use this program to forward udp, so I tried to minimize the overhead..). After the merge(#27), it just works.

There is only one global timer, which finally clears states and close fds. If the relay continues to receive UDP packets, the cleaning up logic will never be executed, thus leading to a resource leak. Morever, the hardcoded TIMEOUT value is 15min, making the problem even more severe.

The solution is simple: set timeout for each socket & set a proper TIMEOUT value.

Thanks for the reply, I'll try it!

Hi, the next one crashes with the following error, is there any solution?

thread 'tokio-runtime-worker' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 98, kind: AddrInUse, message: "Address already in use" }', src/udp.rs:29:88

I tried to fix it by tweaking the timeout value, but I wasn't able to set the timeout for every single socket, thank you!
