Ubuntu 报告触发器重新启动并以崩溃结束

我有一台机器，它整夜不停地运行加密挖矿软件 gpu。有时它会多次触发 ubuntu 报告，直到崩溃。它首先创建 root 用户切片，然后开始触发报告：

Mar 24 01:27:35 r9 systemd[1]: Created slice User Slice of root.

Mar 24 01:27:36 r9 systemd[13968]: Startup finished in 35ms.

然后它关闭它：

Mar 24 01:27:36 r9 systemd[1]: Stopping User Manager for UID 0...
Mar 24 01:27:36 r9 systemd[13968]: Stopped target Default.

Mar 24 01:27:36 r9 systemd[1]: Stopped User Manager for UID 0.
Mar 24 01:27:36 r9 systemd[1]: Removed slice User Slice of root.

它会不断重复，直到系统因内存问题崩溃：

"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message"

有人能告诉我“ubuntu 报告的报告触发器”是什么吗？为什么它会反复启动和停止？

我正在使用 ubuntu 18.04 和内核 5.4.0-54-generic。

问候

答案1

Ubuntu 报告 (https://github.com/ubuntu/ubuntu-report) 是一项服务，它：

此工具将收集并报告当前硬件、分区和会话信息的指标。此信息不能用于识别单台机器，并且在发送到服务器之前显示。

每次启动时都会运行。您的输出似乎显示正常行为。

您的输出似乎没有显示它“反复启动和停止“在一次启动周期内。如果确实如此，那将是一个错误。

请注意，此工具100% 开源。您可以审核代码以查看其功能。您可以轻松查看发送的报告（尝试一下：ubuntu-report show或查看man ubuntu-report。这里没有秘密，也没有个人信息。

答案2

崩溃是由于将数据刷新到磁盘花费的时间太长并导致“echo 0 > /proc/sys/kernel/hung_task_timeout_secs”错误造成的。ubuntu 报告与此无关

通过设置以下变量来修复它

vm.dirty_background_ratio vm.dirty_ratio
