| Description |

This happen sometime since the 1.8 on some server, more often if they are highly loaded. All the players get a timeout, it's unreachable, but.. all the command from console work and the server continue to display /tps right but /stop never end. The server cannot be joined anymore, the CPU usage increased to 100-400% (depending of netty thread). As you can see on the screen there is 2 netty thread in infinite loop, still on the same task. Thanks. |

Not really, 100% = 1 thread On this Xeon 3 I can get 800% (8 thread) and the main loop can go up to 200% (2 thread but 1 core), if all netty are looping I can get 400% (100% by netty thread) the other server will run on the 2 core left (2 core = 4 thread = 400% xD). |

@conormcs In most GNU utilities, CPU usage is measured in cores so 100% = 1 core fully used and 400% = 4 cores fully used. |

TBH I have no idea how the CPU usage could ever display as 400% but meh. |

I'll do, I've added the snaphot in the rar you dont get what you want in ? Tell me what you mean by samplers ? Here is the dump http://pastebin.com/9TiDeMDP |

Not what I meant but a thread dump may work too for now |
