Rust Server Unresponsive...Fix Please?

Hello guys. I’m new on this site and i like it…I find it very useful…So: I opened a Rust server a few days ago, I put Rust++ on it… but there is an error everytime I let the server to be open for more than 2 hours. It gives me an error in the server console, saying that the server is unresponsive. I can either let the server close by itself or restart it. It’s very annoying because I can’t make it be 24/7 because of this error. Does anyone have a fix for it? I don’t think that I am the only one who gets that error…
BTW, here is a screenshot of the error. I’m really not looking to advertise the server… I just want a fix for it: http://gyazo.com/6b6be7560bc65acdda1c253fbd7b2833

The force is strong with this one.
