Proxmox:节点70的负载，2个容器没有响应，但是top没有显示任何信息

Question

我有个大问题。如果我不重新启动节点，我的一些基于Proxmox的LXC容器在2天后就没有响应。

这种情况总是在晚上的同一时间发生(我猜在一个容器上发生了一些事情，导致了沉重的负荷)。

问题是：top/atop/htop没有显示任何东西。proxmox节点对ssh命令没有问题，但5个节点中有2个节点没有真正响应(我可以使用SSH登录，但不能输入命令)。

我还必须进行“硬”重新引导，因为重新启动不起作用(LXC-容器在40分钟后不会停止)。

这是我的PVE版本：

Answer 1

lxcfs: 2.0.0-pve1 1有一个让容器挂在内核中的错误。

我已经通过更新到lxcfs: 2.0.0-pve2来解决这个问题。看看这里：

Answer 2

我们运行的内核与您拥有的内核相同，并且LXC容器将完全挂起。同一主机上的KVM机器仍在运行。它可以是什么，以及如何使LXC容器在不重新启动主机的情况下再次响应？

即使在主机上运行以下命令，也不会继续运行：
