My friends and I log onto my vanilla 1.12 server but it keeps closing randomly. Everyone who is on the server is logged off. My server has been dong this for the past months and I have not been able to find a way to solve it. The server is laggy at times and is sometimes gets rid of recent progress. Can anyone can look at my latest crash report and tell me what is wrong and how to fix it? -thanks
