    damn... we try to change kernel, but nothing change! with gc verbose on, all seems to works good, so thread are sending correctly but mc still crashes every 2 h!

    can u tell me dedicated server configuration?

    Same problem since today.

    My server runs since 2 months without any lags and any other problems, but since Sunday there are many problems.
    (But I don't installed new plugins in the last time, only updated CraftBukkit)

    Might not be helpful: I had this problem only once, when I raged about my world being covered with snow and I used "//thaw 10000" that caused the server to crash and to give me the "Read Time Out" Error. Possibly it's related to plugins and/or the the server maybe overloaded?
