我安装了 Xubunut16.04，配备 16GB RAM 和 20GB 加密交换空间。
当我开始用
configure
make -j
在终端中，我可以在面板负载监视器中看到
- 所有核心都达到 100%
- 内存在大约 20 秒内达到 100%
- Swap 显示仍为零。一旦内存达到 100%，整个 PC 就会冻结。我无法通过键盘/鼠标执行任何操作。我无法进入另一个终端。我无法从另一台 PC 通过 ssh 登录。HDD 灯亮起，磁盘正在旋转。
我每次都能重现这种情况。我已经等了 5 个小时，但没有任何变化（它没有撤销）。我需要进行硬重置。
我在论坛上读了很多东西，找到了关于 Swap 和 cypttab 的提示。从命令中，我在开始编译之前可以检查一切正常。
- Swap 设置只是标准默认设置。命令的 UUID和的
blkid内容/etc/fstab一致etc/cypttab 交换似乎已打开
swapon --show
名称.....类型....大小使用优先级
/dev/sm-0 分区 15.2G 0B ..... -1
由于 PC 处于空闲状态，USED=0B 似乎没问题。不知道 PRIO=-1 是否可行。
- cryptsetup 似乎正在工作 cryptsetup status cryptswap1 /dev/nmapper/cryptswap1 处于活动状态并正在使用 [...]
我尝试设置 vm.min_free_kbyptes 和 vm.swappiness 的值
sudo nano
vm.swappiness 40
vm.min_free_kbyptes=240000
这是崩溃的系统日志部分

我该怎么办？Ubuntu 安装这么容易崩溃，这正常吗？使用用户权限崩溃？
答案1
我找到了一种防止系统崩溃的方法（见下文）。但我希望还有其他方法，因为上面的帖子意味着一个简单的用户空间命令“make -j”就可能导致整个 PC 崩溃。为什么像 Linux 这样安全的操作系统却无法防止这种情况发生？
当我执行以下操作时系统不会崩溃：
- 从文本控制台编译（ctrl-alt-f1）
- 将变量 TEMPDIR 更改为磁盘上的路径
mkdir /home/username/tmp export TEMPDIR=home/username/tmp
也许有人可以解释为什么这样做有效。
[更新]：它能工作，但只是有点。当使用例如“make -j4”时，系统速度会快得多，因为在运行无限作业时，所有这些缓存、任务终止都被省略了。运行上述更改后，系统不会崩溃，但对于其他用户或同一用户的其他终端来说，系统会严重停滞。
