    Hello there.

    I have a little problem..

    My server, with plugins usually takes 2-3 gb of ram. works fine for some hour.. and then suddenly it just increases with around 10 mb / sec upto all my memory is taken (8 gig)..

    Inacitvated all plugins and it still does the same, works for some hours and then suddenly steals the memory.
    Downgraded to java 6 to see if it was that, but nothing..
    Minecraftserver logs doesn't show any probs..

    Anyone heard about this problem before maybe? cant find any issue or sulution.

    Tried to inactivate weather and mobs but that wont help

    Bought 8 more ram that i gonna install tomorrow and gonna se what happens..

    Server specc:

    I got the same problems. I don't know if its just 1.3.1 because i start rebuilding my server 1 august. I had an high populated server 1 year ago.

    Now i got the same problem My server restart automatic at 10:00 AM its I made this printscreens around 14:00 PM

    Is this just 1.3.1 or plugin failures ?

    Server stats: *6 min after restart server*


    Plugins that i use:

    Ram is going wild after 4 Hours. Only just 4 builders online.


    Server in normal condition after server restart:


    Please drop your comments below, If its maybe an plugin please let me know.

    CPU: AMD FX-4100 X4 4.0GHz (Bulldozer) is no good for servers, Java does not run well on Bulldozers at all.. even a intel I3 would be suitable atm.
    I realised in 1.3 that it's been eating RAM so badly, I think it's a poor build by Bukkit to be honest by R4 we will have surely a more optimised version.
    Your ram is good I got the same one, I'm 100% sure that a G.Skill 8GB ram should not be affected like this at has to be bukkit and not us.
    I would also remove OrebFuscator its just one of the main reasons of lag 99% of the time.

    well have a I5 on 3800 mhz if the cpu fails.. But it seems to runs really good on the bulldozer anyway, doesn
    t use much cpu at all and works really fine.. its just the memory stealing.. and that cant be cause of my cpu.

    It seems working nice again. Don't know why i did not uninstal any plugins. Only add few. ...

    i insterted 8 gig ram more yesterday. but server does the same, takes 14 gig ram now instead of 8.. insane.. one world, does the same with or without plugins... even tried to reinstall java and whole window

    Its kinda insane, server takes 2,5 - 3 gig memory. stays there for 2-3 hours, then its studdenly tics slow up to maximum memory....

    There we go again:


    And the ram usage will grow every spike.

    Dont forget that your server takes more memory during "nights" when monsters spawns and need memory. So the suddenly drops can be when they die and dont need the memory usage.
