(Get the code!)
I've recently been wondering why my kvm server runs out of memory when I try to run minecraft server on one virtual machine. It looks like the problem is caused by this bug. I'm now running 3.2.0-36 on the host and virtual machines but I still cannot run minecraft on the virtual machine without idr_layer_cache growing endlessly until the server runs out of memory.
The server is running stable if I don't try to run minecraft. If I do it usually runs out of memory in a few hours.
On the server I have six virtual machines running.
The server has 18GB memory and virtual machines use only 8GB.
I have exported home directories from the server to virtual machines using NFSv3.
The filesystem for home directories is formatted as XFS.
On the minecraft virtual machine I have 2GB memory and a lvm partition for minecraft and other stuff.
The lvm partition resides on the same physical disk as the home directories.
