I host my own minecraft server and have been for well over a month with no issues until early tonight my friend started running around the server and it suddenly crashed and has not been working correctly since. Even while I am running the server on this computer minecraft says that it cannot be reached, also it refuses to let me allocate more than 1024 mb to my server even though I am using a bat file. This is the code I was attempting to use. @echo off java -Xms4096M -Xmx4096M -jar Minecraft_Server.exe gui pause However it refuses to let me allocate that much memory and not even 2048 I cannot successfully run the bat file with anything greater than 1024mb I have 8 gigs of ram in my system and that it was my computer always shows, I am also using 64 bit java. Any help would be appreciated since this is a very developed server that has many painstakingly created buildings and inventions and I would hate to permanently lose it due to a server problem. This problem persists even after rebooting my computer, their have only ever been 3 people on the server so I do not think I should have any trouble keeping up whatsoever.
