LowMemoryKiller正在杀死系统应用程序的负载并迫使用户死亡，但“免费”表示有足够的​​内存

一段时间以来，我遇到了一个问题，关键的系统进程被LowmemoryKiller / OOM强制杀死。

在获得帮助之后，我添加了一个500 MB的交换文件，该文件在几天前就可以正常运行，以尝试减少内存压力和lowmemkiller触发器（此处提供线程详细信息）。的输出free显示出额外的500 MB空间，我认为这足以防止任何低内存问题强行杀死系统进程。

但这并没有帮助。突然，我突然又突然得到了一个相当恶毒的“所有东西都被LowMemKiller杀死”，在短短100秒内创建了大约6个核心转储文件，随后用户空间崩溃，内核（dmesg）日志表明该文件很低内存问题是唯一报告的问题，即使这次有大量交换可用并且被系统识别（请参阅free下文）。

这是重启用户空间dmesg >dmesg.txt后不久的相关部分init。在日志的第一部分，经过几秒钟的长时间，什么也没有发生。当用户空间在2105-2208的100秒内被杀死时，没有任何事前发生，也没有任何原因的提示。

但是swap它很活跃，目前还不清楚发生了什么。free恢复用户空间后立即输出：

Swap:       687060        19024       668036

不知道发生了什么。FWIW：（1）交换可用且已启用，但由于内存不足而在事件中未使用，因此不予使用；（2）某个进程突然决定需要大约1GB的RAM并在前台运行，从而导致尝试交换关键但优先级较低的系统进程的尝试失败；（3）不可预测的剧烈内存泄漏。

我不知道从这里去哪里。

该手机以CyanogenMod 11 M6为根基运行，并具有1GB内存，并且这些应用程序是非常标准的-Firefox，whatsapp，没有异常，没有奇怪的“扭曲”，没有奇怪的改装应用程序。

我该如何解决这个问题？

更新我意识到我可以找到相关的核心转储。/data/tombstones包含6个核心转储，这些转储都是在100秒钟内发生的，该内存转储是在内存不足的情况下发生的dmesg。核心转储文件大多显示分段错误（SIGSEGV），但每个转储的拥有过程不同：

同一文件夹中过去的核心转储也是如此，例如，线程所有者包括“图库”。一些显示SIGABRT而不是SIGSEGV。除此以外，可能还需要开发人员能力。我应该怎么做才能找出原因？

Android具有内置的ram管理系统，可以很好地完成工作。公羊管理应用程序臭名昭著的仅仅是蛇油。最坏的情况实际上是对其运行过程有害。我假设此内存杀手级应用是您问题的根本原因。解。重新刷新设备，删除低内存应用，然后查看其行为

我不太了解问题是突然发生的还是仅在CM11中发生。我的第一个建议是恢复出厂设置并运行一系列基本的应用程序，从Play商店安装的次数越少越好，并查看是否发生问题。如果确实如此，则CM正在为LMK运行一些非常激进的值（可能更新为更新的值或使用修改后的值构建rom）。如果这并不意味着您的应用程序之一告诉android，则需要ram和android（可能是由于dalvik或hwui堆设置不正确，或内核lmk值不佳）而引起的，只是开始大规模杀害进程。

如果您购买时未在手机上安装此应用程序，而是随后安装了该应用程序，则执行此应用程序的应用程序可能是恶意软件。我建议直接去Verizon，让他们弄清楚发生了什么。它可能会花费很多，但如果可以修复，则很值得。
