    After I go to sleep(about 4 hours of bukkit being the only thing running), the server becomes unresponsive but cmd prompt is still open, and everyone is kicked and cannot join. The server is fine as long as im doing something on the computer, as simple as reading a webpage, but when bukkit is the only thing running for a while it F's up. Also there were about 12 lines of "connection reset" which appears when someone leaves or joins, and since it didn't show "Blahblahblah.disconnected.quitting" I'm assuming they were kicked/lagged out from the server having this problem. Help? Thank you.

    I have no clue what this means.
    My Java:
    Code:
    java version "1.6.0_26"
    Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
    Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)

    You should update java from 1.6 to 1.7 JDK, just a though. Also the read timeout errors stopped occuring when I allocated less RAM for some reason, doesn't make much sense to me..
     
  4. Would suggest to monitor your Ram and IO utilization (and overall server performance)!
    If you dont know how -> websearch!

    Since it sounds like your running it on your computer. Make sure ALL powersaving etc is disabled
