Hi, my server is a server that i use to play with about 3-5 of my friends. I have been having a problem where every 5 - 15 minutes my server would randomly shut down. I have checked the logs and the only thing out of the ordinary is going too fast, due to getting speed.90 for 1 second from a command block. the plugins i have are: Emerald tools, essentials (all of them), vault, holographic display, item edit, jobs reborn, perm ex, shopkeepers, world edit. Any and all help will be appreciated.
