ok, so I have a server hosted by mcprohosting, for me and my friends to play on. for some reason, it keeps crashing. my guess is that it doesnt have enough ram (currently 768 mb). I will be upgrading the ram on it fairly soon anyway, but I dont know java or coding too well, so I just wonering is it the ram, or is it something else, like a bug. Also, it never crashed before we updated to 1.8 prerelease 3.
