Help Me! Internal Exception: Java.net.SocketTimeoutException: Read Time Out

Well, I am having a problem on my server, that I have never experienced before. about every hour or so, the server freezes, crashes, gives everyone the error: Internal Exception: Java.net.SocketTimeoutException: Read Time Out, then when people try to connect, it gives everyone end of stream errors for about a minute, then everything is fine. The server dosent shutdown, there are no errors in the console besides end.of.stream for all the players that get kicked, but other than that, I cant tell whats causing it. I didn't have the problem in vanilla, and I tried adding them 1 by 1, and when I finally put vault in, and all the plugins that depend on it, it has the same error, about every hour. the problem is, Ive heard that vault can cause it, or some of the plugins that run on vault. Please help me if you can, I would gladly repay you for your help.
