    要解决这个问题，首先确认系统日志中的错误信息和堆栈跟踪可以帮助我们理解问题的原因。根据提供的日志，可能的问题原因有：

    1. 页表访问权限不足：#PF: error_code(0x0011)表示硬件错误，可能是由于页表访问时权限不足导致的。

    2. 内存泄漏：note: kworker/10:2[499502] exited with irqs disabled和note: kworker/10:2[499502] exited with preempt_count 1表明任务在运行过程中遇到了中断，但未释放内存资源。这可能导致系统频繁重启，进而造成频繁死机。

    3. 进程管理问题：CPU: 10 PID: 499502 Comm: kworker/10:2 Tainted: P D OE 6.5.0-41-generic #41表明存在一个名为kworker/10:2的任务，其被分配了CPU资源，但没有正确释放这些资源。

    为了解决这些问题，可以尝试以下几个步骤：

    1. 检查是否需要提高页表访问权限，并确保所有相关用户都具有适当的权限。

    2. 调整任务的优先级，看看是否有更有效的调度策略来减少不必要的中断。

    3. 分析任务的状态，查看是否存在长时间占用大量内存的情况，以及是否存在内存泄漏。

    4. 如果是内存泄露问题，可以考虑使用垃圾回收机制（如Java的Garbage Collection）来自动释放不再使用的内存空间。

    5. 对于页表访问权限不足的问题，可以通过修改BIOS设置、安装安全补丁等方法修复。

    6. 使用性能分析工具（如Valgrind、GDB）来检查内存管理和页面大小控制等方面的问题。

    具体的解决方案将取决于问题的具体原因。如果有更多细节，可以提供更多关于系统的具体配置和环境的信息。
