Yes Do you still have these problems if you run a Minecraft server without CraftBukkit? I do not know. With 32 people after several minutes no one can log in, the server is running all the time without lag. According CommandBook server has allocated 4GB of RAM and uses 1GB, CPU usage around 30%. The fewer people on the server = login work longer. Has anyone a solution? The problem still exists in version 823...

Says your out of memory for the server. Try allowing the server to use more RAM, or giving it a wider spectrum instead exactly 4 Gb. Best bet would be to experiment with your allocation amount.
I tried: -Xms4096M -Xmx4096M -Xms6144M -Xmx6144M -Xms2G -Xmx4G -Xms512M -Xmx2048M -Xms128M -Xmx6144M When error occur the server never uses more than 1GB of RAM I've also updated to 826 No change :/
